Help with Tool Calling

[1htz2]

I am building a tool and need a model about ollama that supports tool calling. I have tried with qwen3:8b and the tool is not called. Then I thought that I have to define the model with a .json file before and set supports_function_calling and supports_tool_choice to “true”. I did that, but it doesn't change anything. This is what the logs in the docker container look like:

Selecting single tool from tools: []
Chosen tool: None

With llama3 the tool call works partially well. Is it because certain models are defined and re-registered by onyx itself beforehand?

        "ollama/qwen3:8b": {
        "max_tokens": 32000,
        "litellm_provider": "ollama_chat",
        "supports_vision": "false",
        "supports_function_calling": "true",
        "supports_parallel_function_calling": "true",
        "supports_tool_choice": "true",
        "mode": "chat"
      }
