Streaming Callback: awaiting .output() if not providing a format

[cabljac]

I was using the generate method.

As far as I understand, we know that a stream has finished when .output() resolves. However when you don't provide an output parameter (as i just want to use .text() in the streaming callback) it seems like .output() will reject:

>  [ERROR]  bolt-app UnknownError: No JSON object or array found in model output: (....the llm text response here, which is what i wanted)```
