org.apache.kafka.common.errors.GroupAuthorizationException: Not authorized to access group: Axon.Streamable.Consumer-070e77bc-b2a6-4f78-a659-c44dcbdd8f9a


Probably something in your Kafka configuration. Any reason you need a cluster? I used clusters before locally, but Kafka can me memory hungry, so most times it’s better ro run a single instance locally.
