Spotify data import - "Some listens were rejected"

Hi all! I was importing my listening onto ListenBrainz, and it’s said some of my listens can’t be imported - roughly 70000. However, it doesn’t seem to say why. I imagine at least some of it may simply be down to music simply not being on MusicBrainz (which I can try my hardest to add!) but I didn’t know if it’s possible to get reasonings for why each one failed?

Looks like roughly 70,000, not 7000.

I don’t think them being missing from MB would be the reason. I have plenty of Spotify listens that aren’t linked to a MB recording.

I had this issue as well, just this morning.

Missed a zero and realised after I closed the tab earlier :’)

What would the reason be? Worth trying again, or nay?

Have you tried to use ListenBrainz - Unmapped Listens with Spotify Links

I’m not sure; I tried again as well, and got the same error with the same number of listens imported. So I don’t think it’s a server timeout or something like that, maybe Spotify recently changed the format of their data export? Would be cool to get a sample JSON of what ListenBrainz expects during an import.
