Import: Cannot read properties of null (reading 'id')

Description

When importing my "Extended Streaming History", it seems that I have a corrupt entry in my dataset. All files work but one batch. It stops at 1850/16500, but I couldn't determine the entry yet.

Debugging

Any idea what to look out for? The songs, the importer tries to add, have multiple occurrences in my file. Is the importer adding the tracks in the same order as they are listed in the file? So it would be an entry between object # 1850 and 1973?

I'm also experiencing this with one of my json files on 1.12.0.
