Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

v0.6.43

Ollama Version (if applicable)

0.13.5

Operating System

Windows 11

Browser (if applicable)

Arc 1.85.1.3

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

Selecting a Model Preset should send the configured base model ID to the backend and generate a response.

Actual Behavior

When using a Model Preset, the model ID is sent as undefined to the backend, resulting in "model not found" errors (404 from OpenRouter, 400 from Ollama).

Direct model selection from the dropdown works perfectly with the same models.

Steps to Reproduce

  1. Existing Open WebUI installation via Docker Compose
  2. Configure OpenRouter connection in Admin Settings > Connections (or Ollama)
  3. Navigate to Workspace > Models > Create New Model
  4. Select any base model from dropdown (e.g., anthropic/claude-sonnet-4)
  5. Save the preset
  6. Start a new chat
  7. Select the preset from the model dropdown
  8. Send any message
  9. Expected: Response from model
  10. Actual: "Model not found" error (404/400)

Logs & Screenshots

Browser Network Tab:
Requests show ?id=undefined parameter:

GET /api/v1/models/model/profile/image?id=undefined

Docker Container Logs:

GET /api/v1/models/model/profile/image?id=undefined&lang=en-US HTTP/1.1" 200

No relevant JavaScript errors in console

  • Possibly related to #20329 (also involves undefined references)

I can confirm I am able to reproduce this issue on the latest dev with both an Ollama API and an OpenAI API connection set up in the admin Connections settings menu. https://github.com/open-webui/open-webui/pull/20333 does not solve it upon testing.
