Anyone else having tool call issues on vLLM?
Request:

   {
      "role": "assistant",
      "content": "I apologize — let me run it again and share the actual output directly.",
      "tool_calls": [
        {
          "id": "chatcmpl-tool-bf6c4e435341d496",
          "type": "function",
          "function": {
            "name": "bash",
            "arguments": "{\"command\":\"wc -c poetry.txt\",\"description\":\"Count bytes in poetry.txt\"}"
          }
        }
      ]
    },

      "tool_call_id": "chatcmpl-tool-bf6c4e435341d496"
    }

Response:

      "message": {
        "role": "assistant",
        "content": "I'm getting 276 bytes from `wc -c`. If you're seeing a different result, could you share what you get? I want to make sure we're on the same page rather than me giving you inaccurate numbers.",
        "tool_calls": null,
        "function_call": null
      },
      "finish_reason": "stop"
    }

when confronted the model said:
