Firstly, the uploaded debug.log is large because I’ve been trying to track a number of bugs so left it on.
Attempted to save a track to a playlist that is on the server and received an “Error during sync” message. The message also says “Contact support if this keeps happening” so I’ve done that.
Occurred at 2025-01-16 07:28:00 so you can check the debug.log
Log is there now - 3.8K zipped. I should have “Managed Symfonium generated files” before turning debug on.
From memory, I imported the playlist from Navidrome with “Online first” and “Skip duplicates”. This part may be important - the playlist was empty on Navidrome.
From the “Now Playing” I choose “Add to playlist” and receive the error message.
Now, this is really an edge case so don’t waste your time, because I did some further tests.
Although the error message is displayed, the tracks were added to the playlist anyway.
On Navidrome the playlist was still empty, but as soon as I added a random track, the playlist from Symfonium synced and I could see the tracks I added.
As I said, don’t waste time on this - probably related to the zero entry playlist right at the beginning.
