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

Ollama Version (if applicable)

none

Operating System

Debian 13.0

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

It should use a server from the openapi list, not the server that provides the openapi.[json|yaml|yml...].

Actual Behavior

It uses the server from which the endpoint list is loaded

Steps to Reproduce

  1. Add a new tool with an openapi compatible endpoint which uses different api servers (for example the German "Autobahn API" https://autobahn.api.bund.dev/
  2. Add the tool to a model
  3. Ask something like "Welche Autobahnen gibt es in Deutschland" (Which highways are there in Germany)
  4. Tool call failes because the wrong api server is being used

Logs & Screenshots

Image

As you can see it runs "list-autobahnen" on the server autobahn.api.bund.dev but that doesn't provide the API endpoints

Additional Information

I'll look into it so see if I can maybe provide some commits to get this working correctly

Unable to reproduce, most likely a misconfiguration.
