Sync feature not working question

[Protonosgit]

Hi, I just tried implementing the sync feature of watermelondb with supabase and ran into an issue I cant really fix:
When requesting a sync using the rpovided example snippet to my database it simply fails with: TypeError: Cannot read property '_resetCount' of undefined.
This seems to happen even before a request is even made to my database directly after invoking synchronize.
I tried resetting the whole app multiple times and adding/removing fields but the error persists.

I might be stupid but there is always some data present in the database before requesting a sync inserted by my own sync system. Might this be the problem? Should the database be completly empty before requesting the first sync?

Update: It doesnt work with an empty database either and synclogger shows the same error

Seems to have been a weird import issue on my side and is now solved but there definetly should have been a warning from watermelondb in such cases!
