MinVersionNotReachedException
class MinVersionNotReachedException(val ref: AggregateRef, val minVersion: Int, val version: Int) : RuntimeException
A state read that asked for at least minVersion of ref (read your writes) while the aggregate stayed at version (0 when it has no commit) through the read's wait: the command whose version was asked for has not committed yet. The HTTP state route answers it 409 CODE with the version, and Retry-After.
