How can I know when the tokens are finished?

[pironev]

I created a stream on the server like this:

const readable = new Readable({read() {}});
session.prompt("How to call a function from a module in Python?", {
  onTextChunk(chunk) {
    readable.push(chunk);
  }
});
return reply.send(readable);

But for the client I need to close the stream. So I need to execute readable.push(null);
Is there an event to know when is finished the loop from onTextChunk?
Thank you!

You need to await on the promise returned from session.prompt(...) to know when the generation has finished.
