I’m wondering why in the example you decided to use string type as a User’s primary key and not ObjectId like it is in Task’s primary key. Does it has something to do with
custom_data? So it can be only linked by
objectId ? Can I use ObjectId instead? Does it has something to do with the partition key?
I have tried to change to ObjectId, and I get ERROR during the synchronization (SyncSession Start).
could not evaluate sync permissions with error: cannot compare to undefined (ProtocolErrorCode=206) Partition: user=5f8ad998ed73ed16ea144f62
