Operating System

Ubuntu 22.04

Browser (if applicable)

N/A

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 listed steps to reproduce the bug in detail.

Expected Behavior

The user's bad behavior should report the error message and not produce an exception.

63533c9e3a/backend/open_webui/main.py (L1111)

The exception accesses a metadata dictionary, and in this case its not being created in time due to the exception occurring before line 1078 in main.py

Actual Behavior

A bad request is being sent via the OpenAI API from a client to the openwebui chat/completions API.

The error associated with this message is producing the exception:

During handling of the above exception, another exception occurred:

Steps to Reproduce

Run script using current version of openai (1.72.0)

import httpx
import openai
import os

from dotenv import load_dotenv


load_dotenv()
url = "https://url_to_openwebui/api" 
# Use an incorrect model name to produce the error
model = "meta-llama/Llama-3.3-70B-Instruct"

# Create a non-async client to test the connection
test_client = openai.OpenAI(
    base_url=url,
    # api_key="sk-no-key-required",
    api_key=os.environ.get("OPENAI_API_KEY"),
    http_client=httpx.Client(verify=False)
)

content = "This is a test of the system, please respond with \"Hello... this is how you talk to me\""

response = test_client.chat.completions.create(
                model=model,
                max_tokens=1024,
                temperature=0.7,

                messages=[

Originally created by @tblattner on GitHub (Apr 9, 2025). Original GitHub issue: https://github.com/open-webui/open-webui/issues/12658 ### Check Existing Issues - [x] I have searched the existing issues and discussions. - [x] I am using the latest version of Open WebUI. ### Installation Method Pip Install ### Open WebUI Version 0.6.0 ### Ollama Version (if applicable) _No response_ ### Operating System Ubuntu 22.04 ### Browser (if applicable) N/A ### 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 listed steps to reproduce the bug in detail. ### Expected Behavior The user's bad behavior should report the error message and not produce an exception. https://github.com/open-webui/open-webui/blob/63533c9e3ab41edd7bd4124ef94f6b6dc09aa175/backend/open_webui/main.py#L1111 The exception accesses a metadata dictionary, and in this case its not being created in time due to the exception occurring before [line 1078 in main.py](https://github.com/open-webui/open-webui/blob/63533c9e3ab41edd7bd4124ef94f6b6dc09aa175/backend/open_webui/main.py#L1078) ### Actual Behavior A bad request is being sent via the OpenAI API from a client to the openwebui chat/completions API. The error associated with this message is producing the exception: ``` During handling of the above exception, another exception occurred: Traceback (most recent call last): File

Same issue here. Using API key from user profile.

curl -X POST http://localhost:3000/api/chat/completions \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
      "model": "llama3.1",
      "messages": [
        {
          "role": "user",
          "content": "Why is the sky blue?"
        }
      ]
