Bug Report

Installation Method

Docker

Environment

  • Open WebUI Version: 0.5.9

  • Ollama (if applicable): 0.5.7

  • Operating System: Windows 11

  • Browser (if applicable): Firefox 134.0.2

Confirmation:

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

Expected Behavior:

The result of a native tool call is handed to the model for further processing.

Actual Behavior:

The model does nothing with the result of a native tool call.

Description

Bug Summary:
Native tool calling works in principle, but the the model is not called again with the result. So no answer is generated.

Reproduction Details

Steps to Reproduce:

  • Activate native tool calling for a model (e.g. LLama 3.1 or 3.2).
  • Open a chat and activate a tool.
  • Ask the model something, that triggers the function call.
  • Open Webui creates an empty message, that only contains the details of the tool call, but no further processing by the model.
<details type="tool_calls" done="true" content="[{&quot;index&quot;: 0, &quot;id&quot;: &quot;call_2cf4317d-058f-4b18-b592-578355b950fc&quot;, &quot;type&quot;: &quot;function&quot;, &quot;function&quot;: {&quot;name&quot;: &quot;dice_roll&quot;, &quot;arguments&quot;: &quot;{&#x27;dice_str&#x27;: &#x27;2d10&#x27;}&quot;}}]" results="[{&quot;tool_call_id&quot;: &quot;call_2cf4317d-058f-4b18-b592-578355b950fc&quot;, &quot;content&quot;: 16}]">
<summary>Tool Executed</summary>
