running paperpi creates this error

running "paperpi --run_plugin_func lms_client.scan_servers" also gives the "players_loop" error

Thanks for the updated bug report.

I'll need to take a deeper look into this. I suspect something in the underlying LMS Query library is borked.

Does paper pi start without the LMS plugin enabled?

OrangeTsar commented 7 months ago

It starts without that plugin loaded, and also the problem is intermittent. Sometimes it will start fine, sometimes it gives that error. If I keep trying to start it, it eventually goes.

txoof commented 7 months ago

Are there any other log lines that might be relevant when it fails?

Good to know that the paperpi --run_plugin_func lms_client.scan_servers command also fails.

I'll dig into this to see if I can figure out what's going on.

@OrangeTsar Can you run paperpy with --log_level DEBUG and share any lines around where the LMS plugin crashes?

I think I've zeroed in on where the problem is, but I need some more information about your circumstances.

txoof commented 7 months ago

@OrangeTsar I've updated the QueryLMS library and paperpi. Can you try to reinstall paperpi and see if this fixes your issue?

OrangeTsar commented 7 months ago

Appears to be working. It didn't like a LMS plugin that generated random playlists, but it's all good now it seems.

txoof commented 7 months ago

@OrangeTsar glad to hear it! I'll close this ticket.

Not sure what you mean about the random playlists though. Can you elaborate?
