Actor recovery failure due to invalid gzip-compressed event serialized by JacksonSerializer

Akka Persistence / Event Sourcing
1

I got a strange error on prod. One of persistent entities stopped recovering because of corrupted compressed json stored in event_payload (blob) (Jdbc journal / mariadb).

The responsible serializer is Akka / Jackson Serializer.

The gzip header of the corrupted content differs from other headers.

System is running on Akka vesion 2.6.19.

Any ideas what went wrong?

Nothing we have heard of before, could it be data corruption in the db? Can you manually decompress it with gzip or is the header/data completely broken?
