Random Unhandled error events

[eliaskg]

Can't reliably reproduce it. Seems like it can happen on opening a new project but it also happened while working in a project. I have no ableton.on listeners in my script.

AbletonJS: 3.1.4

Node.js: v18.12.0

Ableton Live: 11.2.10

node:events:491
      throw er; // Unhandled 'error' event
      ^

Error [ERR_UNHANDLED_ERROR]: Unhandled error. ('Message could not be assigned to any request: {"event": "result", "data": true, "uuid": "9e2fd0f9-9bec-4c88-a128-f82b093df901"}')

}

Update: It is definitely happening on every Export of the project.

Update 2: If I implement an error handler, the error gets displayed but the script doesn't crash 🤗:

ableton.on("error", (e) => console.error("Error:", e));

Thanks for raising this issue! These errors usually occur when the script is restarted but Live is still emitting events for listeners that the new instance of the script doesn't know about.

It shouldn't crash the script though. I've just pushed a new version that removes this error event.

@leolabs Awesome, thank you!
