Error when model tries to call tool: "Cannot read properties of undefined (reading 'filter')"

[Mobious]

As the title says, In agent mode, any time the model tries to make a tool call, I get an error from Continue. Otherwise, chat and auto-completions seem to work fine. I'm using a custom LLM server that emulates the ollama format.

config.yaml

name: Local Config
version: 1.0.0
schema: v1
models:
  - name: GPT OSS 120B
    provider: ollama
    model: gpt-oss-120b
    apiBase: http://127.0.0.1:9000/ollama
    roles:
      - chat
      - edit
      - autocomplete
    capabilities:
      - tool_use
    defaultCompletionOptions:
      contextLength: 128000
      maxTokens: 5000
      temperature: 0.5
      topP: 0.95
      reasoning: true

Error message

[@continuedev] error: Cannot read properties of undefined (reading 'filter') {"context":"llm_stream_chat","model":"gpt-oss-120b","provider":"ollama","useOpenAIAdapter":false,"streamEnabled":true,"templateMessages":false}

This is the response my server gives that triggers the error. I've tried to follow what I believe is the expected response format, but I'm not sure if this is the cause or not.

{
    "message": {
        "role": "assistant",
        "content": "",
        "tool_calls": [
            {

                "function": {
                    "index": 0,

                    "arguments": {
                        "dirPath": "/",
                        "recursive": false
                    }
                }
            }
        ]
    },
    "done": false
}

Any pointers in the right direction would be appreciated.

I figured it out. My server was removing fields that had the default value. Since content="", it was not being sent which caused Continue to have issues. Ensure default values were sent fixed the problem.
