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

v0.6.26-cuda

Ollama Version (if applicable)

na

Operating System

Ubuntu 22.04

Browser (if applicable)

Chrome 139.0.7258.155

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

Do the update without throwing an error by Pydantic.

Actual Behavior

Update fails due to Pydantic Error.

| pydantic_core._pydantic_core.ValidationError: 20 validation errors for KnowledgeFilesResponse
| files.0
|   Input should be a valid dictionary or instance of FileMetadataResponse [type=model_type, input_value=FileModel(id='4e163130-89..., updated_at=1755356834), input_type=FileModel]

Steps to Reproduce

  1. Go to Workspaces/Knowledge
  2. Create a knowledge base and add files
  3. Select knowledge base after creation
  4. Try to change the Access Control

The errors are coming to the log as soon as the pop up opens.

Additional Information

You don't get any visible errors in the UI. The requested change just isn't saved.

In the chrome dev console you can see the 500. See screenshot.

Image

The problem is also reproducible via API.

FTR - I do not use Ollama. I use vLLM in the background which should make no difference for this issue.

Originally created by @stelterlab on GitHub (Sep 6, 2025). Original GitHub issue: https://github.com/open-webui/open-webui/issues/17244 ### Check Existing Issues - [x] I have searched the existing issues and discussions. - [x] I am using the latest version of Open WebUI. ### Installation Method Docker ### Open WebUI Version v0.6.26-cuda ### Ollama Version (if applicable) na ### Operating System Ubuntu 22.04 ### Browser (if applicable) Chrome 139.0.7258.155 ### 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 Do the update without throwing an error by Pydantic. ### Actual Behavior Update fails due to Pydantic Error. ``` | pydantic_core._pydantic_core.ValidationError: 20 validation errors for KnowledgeFilesResponse | files.0 | Input should be a valid dictionary or instance of FileMetadataResponse [type=model_type, input_value=FileModel(id='4e163130-89..., updated_at=1755356834), input_type=FileModel] ``` ### Steps to Reproduce 1. Go to Workspaces/Knowledge 2. Create a knowledge base and add files 3. Select knowledge base after creation 4.

don't get any visible errors in the UI. The requested change just isn't saved. In the chrome dev console you can see the 500. See screenshot. <img width="1324" height="153" alt="Image" src="https://github.com/user-attachments/assets/fa16a4a3-5a61-4d39-b2bf-99fe64791fd0" /> The problem is also reproducible via API. FTR - I do not use Ollama. I use vLLM in the background which should make no difference for this issue.
