Check Existing Issues

  • I have searched the existing issues and discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

0.6.15

Ollama Version (if applicable)

No response

Operating System

Windows 11

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

Expected Behavior:
The action function should execute successfully, process its logic, and interact with UserValves settings without encountering a TypeError. The user["valves"] should be a mutable object (e.g., a dictionary or a Pydantic model instance) allowing for item assignment.

Actual Behavior

Steps to Reproduce

Steps to Reproduce:
Prerequisites:

Ensure Docker and Docker Compose are installed on your system.
Familiarity with basic terminal/command prompt commands.
(Optional, but recommended for full testing): An API key for OpenAI or Anthropic, or a local Ollama instance running if you intend to test actions that make LLM calls.
Set up OpenWebUI (Clean Installation of v0.6.15):

If OpenWebUI is already running:
Navigate to your OpenWebUI installation directory (where your docker-compose.yml file is, or where you typically manage your open-webui container).
Stop and remove any existing OpenWebUI containers and its associated volume to ensure a clean slate (this will delete all existing chat history and data – BACK UP if needed):
Bash

docker compose down -v

OR (if using direct docker run):

docker stop open-webui

docker rm open-webui

docker volume rm open-webui # WARNING: This deletes all data!

(Optional, but highly recommended for thorough cleanup): Prune all unused Docker data. Use with caution, as this removes ALL unused Docker objects.
Bash

docker system prune -a --volumes
Install a fresh instance of OpenWebUI v0.6.15:
Create a new, empty directory for OpenWebUI (e.g., mkdir open-webui-test && cd open-webui-test).
Create a docker-compose.yml file with the following content (or use an equivalent docker run command):
YAML

version: '3.8'
services:
open-webui:
image: ghcr.io/open-webui/open-webui:v0.6.15 # Explicitly specify the version
container_name: open-webui
ports:
- "3000:8080"
volumes:
- open-webui-data:/app/backend/data # Persistent volume for data
environment:
# Ensure this is set for stable sessions, use a strong random key
- WEBUI_SECRET_KEY=your_secure_random_secret_key_here
# Optional: If connecting to local Ollama
# - OLLAMA_BASE_URL=http://host.docker.internal:11434
restart: always
volumes:
open-webui-data:
Save the file.
Pull the specific Docker image and start the container:
Bash

docker compose pull
docker compose up -d
Wait a few minutes for the container to start.
Access OpenWebUI and Create User:

Open your web browser and navigate to http://localhost:3000.
Register a new user account (e.g., testuser / password). Log in.
Install Action Functions (Select one to test at a time):

Open your terminal/file explorer and locate the open-webui-data volume's mounted path (e.g., your-open-webui-test-folder/open-webui-data or a Docker volume path if not directly mounted). Inside, navigate to or create the functions directory: /path/to/open-webui-data/_data/functions/.
Choose one of the following failing action functions and paste its code into a new .py file (e.g., add_to_memory_action.py, smart_summarizer.py, message_processor.py, explain_like_im_5.py) inside this functions directory.
For "Add to Memory Action Button": Use the original, unmodified code you previously provided (before any commenting out).
For "Smart Summarizer": Use the original code you provided.
For "Message Processor Action": Use the original code you provided.
For "Explain Like I'm 5 (Enhanced)": Use the original code you provided.
Restart OpenWebUI after adding the function file:
Bash

docker compose restart open-webui
Enable the Action Function in OpenWebUI:

Log back into OpenWebUI (http://localhost:3000).
Go to Admin Settings (⚙️) -> Functions.
Find the newly added action (e.g., "Add to Memory Action Button," "Smart Summarizer," etc.).
Toggle the switch to "Enabled".
(Optional, but good for testing): Go to Admin Settings (⚙️) -> Models, select the model you are using, and ensure the function is also enabled for that specific model, or enable functions globally if that option is available.
Trigger the Action and Observe Error:

Go to a chat session.
Send a message to any LLM (e.g., "Hello").
Click the action button that appears under the message (for the action you just enabled).
Immediately observe the terminal where your Docker Compose logs are running. You should see the TypeError: 'tuple' object does not support item assignment traceback.
Also, note if any expected UI notifications or changes from the action itself are missing or incomplete.
