Unexpected error on server: Could not read latest stream's prepare. That should never happen.

Hi,

we are getting such errors time after time when trying to read stream (EventStoreConnection.ReadStreamEventsForwardAsync):

“ClassName”: “EventStore.ClientAPI.Exceptions.ServerErrorException”,

“Message”: “Unexpected error on server: Could not read latest stream’s prepare. That should never happen.”

We updated our cluster to Event Store 3.9.1.0 lately.

Could this be related?

Or does this indicate somewhat data corruption?

What could be done to fix the issue?

Thanks.

Hi Vytautas

This is more than likely related to the other post you created.

Have you had a chance to recreate your indexes, and if so, are you still seeing this?

Hi Hayley-Jean,

we are still in progress on rebuilding indexes, but probably you are right.

Thanks for your help.
