Yeah, I’m also having trouble submitting AcoustIDs via Picard:
E: 23:00:15,737 webservice._handle_reply:407: Network request error for http://api.acoustid.org:80/v2/submit: Error transferring http://api.acoustid.org:80/v2/submit - server replied: INTERNAL SERVER ERROR (QT code 401, HTTP code 500)
E: 23:00:15,738 acoustid.manager._batch_submit_finished:134: AcoustID: submission failed with error 'Error transferring http://api.acoustid.org:80/v2/submit - server replied: INTERNAL SERVER ERROR': internal error
D: 23:00:15,738 acoustid.manager._batch_submit:100: AcoustID: submitted all fingerprints
BTW, there is a small bug in Picard where even when submitting the AcoustIDs fails, the program still prints “AcoutsIDs successfully submitted.” in the status bar. The last log line quoted above also doesn’t make sense since the operation failed.
