One solution I see for this problem is to call openai.beta.threads.runs.retrieve.
This PR fixes this bug and allows multiple toolCalls to return, so that calls can be listened to in toolCallCreated and toolCallDone, thus avoiding polling retrieve and improving efficiency.
In addition, with this modification, users no longer need to manually assemble the arguments string, they only need to use function.arguments in callTool in the toolCallDone callback.

stream.on("toolCallDone",async (toolCall) =>{
  console.log(toolCall.function.arguments)
})

Thanks for the PR and really sorry it took us so long to action. I've merged your change in a separate PR so I could make some minor style changes.

This will be included in the next release #1028

@RobertCraigie it's not cool, wait is too long and the new PR will cause developers to give up more contributions because it is difficult to track contributions, however the problem was solved
