to fix this I had to reset the environment, let the record tables be recreated and then re-add the recordName and modifiedTimestamp indexes for the public database. exporting the environment schema and then reimporting didn't work.

This is happening to me in production, but not the development environment. CloudKit Dashboard also display an error when I try to query the affected Record Type. Any proper solution to this scenario? Ok in Development, fails in Production?

no solution yet. if it happens in dev then you can reset the environment. in prod you are screwed.

still happening in iOS18.3.1
