I have searched for any existing and/or related discussions.
I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

0.6.28

Ollama Version (if applicable)

0.11.10

Operating System

Ubuntu

Browser (if applicable)

No response

Confirmation

I have read and followed all instructions in README.md.
I am using the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have included the Docker container logs.
I have provided every relevant configuration, setting, and environment variable used in my setup.
I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
Start with the initial platform/version/OS and dependencies used,
Specify exact install/launch/configure commands,
List URLs visited, user input (incl. example values/emails/passwords if needed),
Describe all options and toggles enabled or changed,
Include any files or environmental changes,
Identify the expected and actual result at each stage,
Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

Added a filter function and verified its correct operation

Actual Behavior

First, thank you to all the developers who contributed to openwebui. I am not a professional developer, but I enjoy the functionality of openwebui, and the following issues occurred while trying out the filter function.
I implemented Filter Function v1 and encountered an error during notes editing, as shown in the log: "AttributeError: 'str' object has no attribute 'ge'".
I then modified my Filter Function to v2, but it subsequently produced another error: "'dict' object has no attribute 'encode'", consistently experiencing format-related issues.
All of these issues occurred while in notes editing mode

Furthermore, enabling the Filter also causes Gemma3 to fail to load images.
Disabling the Filter restores normal functionality for both notes and Gemma3’s image recognition, but I require the Filter’s functionality

Steps to Reproduce

add filter funtion

v1

from pydantic import BaseModel
from typing import Optional


class Filter:
    # Valves: Configuration options for the filter
    class Valves(BaseModel):
        pass

    def __init__(self):
        # Initialize valves (optional configuration for the Filter)
        self.valves = self.Valves()

    def inlet(self, body: dict, __user__: Optional[dict] = None) -> dict:
        keywords_to_remove = [
            "tony",
            "tom",
            "alice",
            "hank"
        ]
        last_message = body["messages"][-1]["content"]
        for keyword in keywords_to_remove:
            last_message = last_message.replace(keyword, "")
        last_message = last_message.strip()
        body["messages"][-1]["content"] = last_message
        return body

    def stream(self, event: dict) -> dict:
        for choice in event.get("choices", []):
            delta = choice.get("delta", {})
            if "content" in delta:
                content = delta["content"]
                replacements = [
            "tony",
            "tom",
            "alice",
            "hank"
                ]
                for string_to_replace in replacements:
                    content = content.replace(string_to_replace, " ")
                delta["content"] = content
        return event

    def outlet(self, body: dict, __user__: Optional[dict] = None) -> dict:
        replacements = [
            "tony",
            "tom",
            "alice",
            "hank"
        ]
        for message in body["messages"]:
            content = message["content"]
            for string_to_replace in replacements:
                content = content.replace(string_to_replace, " ")
            message["content"] = content
        return body

To resolve the AttributeError: 'str' object has no attribute 'get' issue, I released version 2

from pydantic import BaseModel
from typing import Optional, Union
import json


class Filter:
    # Valves: Configuration options for the filter
    class Valves(BaseModel):
        pass

    def __init__(self):
        # Initialize valves (optional configuration for the Filter)
        self.valves = self.Valves()

    def inlet(self, body: Union[dict, str], __user__: Optional[dict] = None) -> dict:
        if isinstance(body, str):
            try:
                body = json.loads(body)
            except Exception:
                return {}

        keywords_to_remove = [
            "tony",
            "tom",
            "alice",
            "hank"
        ]

        if "messages" in body and body["messages"]:
            last_message = body["messages"][-1].get("content", "")
            for keyword in keywords_to_remove:
                last_message = last_message.replace(keyword, "")
            body["messages"][-1]["content"] = last_message.strip()

        return body

    def stream(self, event: Union[dict, str]) -> dict:
        if isinstance(event, str):
            try:
                event = json.loads(event)
            except Exception:
                return {"choices": []}

        for choice in event.get("choices", []):
            delta = choice.get("delta", {})
            if "content" in delta:
                content = delta["content"]
                replacements = [
            "tony",
            "tom",
            "alice",
            "hank"
                ]
                for string_to_replace in replacements:
                    content = content.replace(string_to_replace, " ")
                delta["content"] = content
        return event

    def outlet(self, body: Union[dict, str], __user__: Optional[dict] = None) -> dict:
        if isinstance(body, str):
            try:
                body = json.loads(body)
            except Exception:
                return {}

        replacements = [
            "tony",
            "tom",
            "alice",
            "hank"
        ]

        if "messages" in body:
            for message in body["messages"]:
                content = message.get("content", "")
                for string_to_replace in replacements:
                    content = content.replace(string_to_replace, " ")
                message["content"] = content

        return body

However, an AttributeError: 'dict' object has no attribute 'encode' has now occurred
enabling the Filter also causes Gemma3 to fail to load images.

Originally created by @j820301 on GitHub (Sep 17, 2025). Original GitHub issue: https://github.com/open-webui/open-webui/issues/17495 ### Check Existing Issues - [x] I have searched for any existing and/or related issues. - [x] I have searched for any existing and/or related discussions. - [x] I am using the latest version of Open WebUI. ### Installation Method Docker ### Open WebUI Version 0.6.28 ### Ollama Version (if applicable) 0.11.10 ### Operating System Ubuntu ### Browser (if applicable) _No response_ ### Confirmation - [x] I have read and followed all instructions in `README.md`. - [x] I am using the latest version of **both** Open WebUI and Ollama. - [x] I have included the browser console logs. - [x] I have included the Docker container logs. - [x] I have **provided every relevant configuration, setting, and environment variable used in my setup.** - [x] I have clearly **listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup** (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc). - [x] I have documented **step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation**. My steps: - Start with the initial platform/version/OS and dependencies used, - Specify exact install/launch/configure commands, - List URLs visited, user input (incl. example values/emails/passwords if needed), - Describe all options and toggles enabled or changed, - Include any files or environmental changes, - Identify the expected and actual result at each stage, - Ensure any reasonably skilled user can follow and hit the same issue. ### Expected Behavior Added a filter function and verified its correct operation ### Actual Behavior First, thank you to all the developers who contributed to openwebui. I am not a professional developer, but I enjoy the functionality of openwebui, and the following issues occurred while trying out the filter function. I implemented Filter Function v1 and encountered an error during notes editing, as shown in the log: "AttributeError: 'str' object has no attribute 'ge'". I then modified my Filter Function to v2, but it subsequently produced another error: "'dict' object has no attribute 'encode'", consistently experiencing format-related issues. All of these issues occurred while in notes editing mode Furthermore, enabling the Filter also causes Gemma3 to fail to load images. Disabling the Filter restores normal functionality for both notes and Gemma3’s image recognition, but I require the Filter’s functionality <img width="1023" height="283" alt="Image" src="https://github.com/user-attachments/assets/08cf708f-872e-466d-af26-2e0fc781b479" /> ### Steps to Reproduce add filter funtion v1 ``` from pydantic import BaseModel from typing import Optional class Filter: # Valves: Configuration options for the filter class Valves(BaseModel): pass def __init__(self): # Initialize valves (optional configuration for the Filter) self.valves = self.Valves() def inlet(self, body: dict, __user__: Optional[dict] = None) -> dict: keywords_to_remove = [ "tony", "tom", "alice", "hank" ] last_message = body["messages"][-1]["content"] for keyword in keywords_to_remove: last_message = last_message.replace(keyword, "") last_message = last_message.strip() body["messages"][-1]["content"] = last_message return body def stream(self, event: dict) -> dict: for choice in event.get("choices", []): delta = choice.get("delta", {}) if "content" in delta: content = delta["content"] replacements = [ "tony", "tom", "alice", "hank" ] for string_to_replace in replacements: content = content.replace(string_to_replace, " ") delta["content"] = content return event def outlet(self, body: dict, __user__: Optional[dict] = None) -> dict: replacements = [ "tony", "tom", "alice", "hank" ] for message in body["messages"]: content = message["content"] for string_to_replace in replacements: content = content.replace(string_to_replace, " ") message["content"] = content return body ``` To resolve the AttributeError: 'str' object has no attribute 'get' issue, I released version 2 ``` from pydantic import BaseModel from typing import Optional, Union import json class Filter: # Valves: Configuration options for the filter class Valves(BaseModel): pass def __init__(self): # Initialize valves (optional configuration for the Filter) self.valves = self.Valves() def inlet(self, body: Union[dict, str], __user__: Optional[dict] = None) -> dict: if isinstance(body, str): try: body = json.loads(body) except Exception: return {} keywords_to_remove = [ "tony", "tom", "alice", "hank" ] if "messages" in body and body["messages"]: last_message = body["messages"][-1].get("content", "") for keyword in keywords_to_remove: last_message = last_message.replace(keyword, "") body["messages"][-1]["content"] = last_message.strip() return body def stream(self, event: Union[dict, str]) -> dict: if isinstance(event, str): try: event = json.loads(event) except Exception: return {"choices": []} for choice in event.get("choices", []): delta = choice.get("delta", {}) if "content" in delta: content = delta["content"] replacements = [ "tony", "tom", "alice", "hank" ] for string_to_replace in replacements: content = content.replace(string_to_replace, " ") delta["content"] = content return event def outlet(self, body: Union[dict, str], __user__: Optional[dict] = None) -> dict: if isinstance(body, str): try: body = json.loads(body) except Exception: return {} replacements = [ "tony", "tom", "alice", "hank" ] if "messages" in body: for message in body["messages"]: content = message.get("content", "") for string_to_replace in replacements: content = content.replace(string_to_replace, " ") message["content"] = content return body ``` However, an AttributeError: 'dict' object has no attribute 'encode' has now occurred enabling the Filter also causes Gemma3 to fail to load images. ### Logs & Screenshots

@rgaricano commented on GitHub (Sep 17, 2025):

In first function it is assuming that content always is a string, if it isn't a string then fault when strip or replace.
In second function it create a dict of dict, then it fail when filter is processed in the streaming pipeline (it expect a dict.
Open WebUI's filter system has specific expectations:

inlet and outlet methods receive dict objects representing the request/response body
stream method receives dict objects representing individual streaming events

In first function it only need a str check and if it is then replace (similar as you did in second one: if isinstance(content, str):)

e.g. with valve for strings:

from pydantic import BaseModel, Field
from typing import Optional

class Filter:
    class Valves(BaseModel):
        priority: int = Field(

@rgaricano commented on GitHub (Sep 17, 2025): In first function it is assuming that content always is a string, if it isn't a string then fault when strip or replace. In second function it create a dict of dict, then it fail when filter is processed in the streaming pipeline (it expect a dict. Open WebUI's filter system has specific expectations: - inlet and outlet methods receive dict objects representing the request/response body - stream method receives dict objects representing individual streaming events In first function it only need a str check and if it is then replace (similar as you did in second one: `if isinstance(content, str):`) e.g. with valve for strings: ``` from pydantic import BaseModel, Field from typing import Optional class Filter: class Valves(BaseModel): priority: int = Field( default=0, description="Priority level for the filter operations." ) keywords_to_remove: list = Field( default=["tony", "tom", "alice", "hank"], description="Keywords to filter from messages" ) def __init__(self): self.valves = self.Valves() def inlet(self, body: dict, __user__: Optional[dict] = None) -> dict: """Pre-process incoming chat requests""" if not body.get("messages"): return body last_message = body["messages"][-1] content = last_message.get("content", "") if isinstance(content, str): for keyword in self.valves.keywords_to_remove: content = content.replace(keyword, "") body["messages"][-1]["content"] = content.strip() return body def stream(self, event: dict) -> dict: """Process streaming response chunks""" for choice in event.get("choices", []): delta = choice.get("delta", {}) if "content" in delta: content = delta["content"] if isinstance(content, str): for keyword in self.valves.keywords_to_remove: content = content.replace(keyword, " ") delta["content"] = content return event def outlet(self, body: dict, __user__: Optional[dict] = None) -> dict: """Post-process complete responses""" if not body.get("messages"): return body for message in body["messages"]: content = message.get("content", "") if isinstance(content, str): for keyword in self.valves.keywords_to_remove: content = content.replace(keyword, " ") message["content"] = content return body ```

Thank you for your reply. I used your code and, after adding keywords, it can be filtered, but errors still occur when editing or generating in the Notes function.
Gemma3 can correctly identify images using your code.

@j820301 commented on GitHub (Sep 17, 2025): Thank you for your reply. I used your code and, after adding keywords, it can be filtered, but errors still occur when editing or generating in the Notes function.

That it's because the Notes function processes streaming data differently than regular chat completions. In the Notes editor, streaming responses are parsed from Server-Sent Events (SSE) format , the data comes in as "data: {json}" format and gets processed line by line.

You can replace the stream method to handle both string and dict inputs:

def stream(self, event) -> dict:
    """Process streaming response chunks"""
    # Handle string input (raw SSE data)
    if isinstance(event, str):
        try:
            import json
            event = json.loads(event)
        except (json.JSONDecodeError, TypeError):
            return {"choices": []}

    # Ensure we have a dict to work with
    if not isinstance(event, dict):
        return {"choices": []}

    for choice in event.get("choices", []):
        delta = choice.get("delta", {})
        if "content" in delta:
            content = delta["content"]
            if isinstance(content, str):
                for keyword in self.valves.keywords_to_remove:
                    content = content.replace(keyword, " ")
                delta["content"] = content
    return event
