Error "Specified group generation id is not valid" during consumption

[kiessan]

Hi there,

We quite often experience the error "Specified group generation id is not valid" when consuming messages for some of our topics:

{"throwable":{"file":"/app/vendor/mateusjunges/laravel-kafka/src/Commit/KafkaCommitter.php:20","code":22,"message":"Broker: Specified group generation id is not valid","class":"RdKafka\\Exception"}}

Unfortunately, this causes the consumer to break/fail. We fiddled around with the heartbeat and timeout settings as suggested here. Sadly, it doesn't solve the issue.

Question: Is it possible for the consumer to rejoin the group automatically? If not, any other solution than recreating the consumer?

Thx a lot for your advice!
