Check Existing Issues

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

Installation Method

Pip Install

Open WebUI Version

v0.6.25

Ollama Version (if applicable)

0.11.6

Operating System

Windows 11

Browser (if applicable)

140.0.7339.128

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

When I start open-webui, and the script has already auto-updated openwebui.

Actual Behavior

The package is already installed in venv open-webui, but the console says this: ModuleNotFoundError: No module named 'itsdangerous'

Steps to Reproduce

  1. Install Python 3.12.8,
  2. update pip to new version
  3. install openWebUI via pip
  4. open-webui is up to date script
  5. There were no errors before, only today's latest update caused errors.

@joocoo commented on GitHub (Sep 18, 2025):

I had a similar issue and when reverting back from the latest release to v0.6.28.
I was able to get it operational.

This is what I was using.
uvx --python 3.11 open-webui@v0.6.28 serve

When using the uvx with v0.6.28 there are 291 packages, but now there are 265 packages.

But I see nothing wrong with the uv.lock file. Nor can I see anything in the files listed in the traceback that would hint an issue.

I hope that the following image will be easier to read.

@Marclass commented on GitHub (Sep 18, 2025):

Some middleware in Starlette is trying to import the itsdangerous library but that's only included with a pip install starlette[full] per their docs and not the default starlette. Open-webui uses FastAPI which wraps starlette so it's probably just a requirements.txt getting out of sync somewhere.

Try doing a pip install itsdangerous or a pip install starlette[full] and see if that resolves it.

Someone using uvx also posted a temp fix in the discord to add --with itsdangerous to the uvx command line.

I am not familiar with UV that well but if this does not help, please ignore.
I just am not sure if the uvx command uses the additional packages from the pip install.

I did to a pip install starlette[full] and then attempted to run the latest tag.,

yeah seems like .6.29 on is broken with this. I did that pip install above too and it gives the same error. I'll just wait for a .31 i guess

Same error updating from v0.6.28 to v0.6.30. Mine is a local installation with uv on Ubuntu 22.04. The update removed 27 packages and only 1, open-webui, was added. itsdangerous is one of the 27 packages removed. Going back to v0.6.28 with uv tool install open-webui@0.6.28 turned OWUI on again.
