No Function Arguments in toolCallDone Stream Event Hook

[neilord]

Confirm this is a Node library issue and not an underlying OpenAI API issue

• This is an issue with the Node library

Describe the bug

The ".on('toolCallDone') used on the stream returned by ai.beta.threads.runs.stream" does not return arguments (empty string), only function name:

{
  index: 0,
  id: 'call_id',
  type: 'function',
  function: { name: 'functionName', arguments: '', output: null }
}

To Reproduce

1. Retrieve a run stream with ai.beta.threads.runs.stream
2. Add the .on('toolCallDone') hook.
3. Wait for the response, it does not return with what arguments should the function be called.

Code snippets

const stream = ai.beta.threads.runs.stream(threadId, {
    assistant_id: assistantId,
});
stream.on('toolCallDone', (toolCall) => {
    console.log(toolCall); // no arguments for function
});

Thanks for reporting, we'll look into it!

Isn't this a duplicate of my issue #771?

Just for completeness. In the toolCallDone event with the toolCall.type === code_interpreter, then toolCall.code_interpreter.input is also empty.

As a workaround I'm listening to the event thread.run.step.completed and handling runStep.step_details.type === 'tool_calls' then the input and output properties are both not empty for function and code_interpreter.
