Exact way of reproduction is unclear unfortunately. I have the impression that you need some amount of data in the database for this to occur, in our case 1-2M objects / 15 GB.

In general this error happens during startup of Weaviate, but not always (race condition?), and we had the impression that the error happened more often as we added more data to the database.
