Bug Report

Installation Method

Docker

Environment

  • Open WebUI Version: v0.3.15

  • Ollama (if applicable): v0.3.5

  • Operating System: Unraid 6.12.10

  • Browser (if applicable): Brave 1.69.153

Confirmation:

  • I have read and followed all the instructions provided in the README.md.
  • I am on 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 the exact steps to reproduce the bug in the "Steps to Reproduce" section below.

Expected Behavior:

The model should use the tools and give back the response using tools.

Actual Behavior:

The model does not use tools and generates a normal response.

Description

Bug Summary:
When a tool is selected, errors are produced regarding the tools and the model cannot use the tools.

Reproduction Details

Steps to Reproduce:

  1. Create a tool (I used the default tool)
  2. Select the tool in the model to allow the model to use the tool.
  3. Start a new chat using said model and activate the tool.
  4. Sent a request.
  5. Review response and logs.

Logs and Screenshots
