I'm using beets to submit my collection on acousticbrainz. When I do this, I get the following set of errors:

The errors are coming from the acousticbrainz CLI tool, PKG-version:

I get status 4, 5, 1 and -11 and I can't find in the documentation what they refer to (I actually couldn't find any detailed documentation, where is it?). I also get a ```json.decoder.JSONDecodeError```. I also opened a report on beets: https://github.com/beetbox/beets/issues/3527 , but the error comes from the acousticbrainz CLI tool.
