Problem with the offset update

Hi all!

Faced a problem with the offset update.
I use Kafka and Kafka-connect in Confluent docker containers. I create jdbc consumers in kafka-connect. The consumer itself works correctly.

But when I want to change the offset for the consumer group and pause the connector, the group is still displayed stable in the AKHQ web interface and when I try to change the offset I get an error:
“Internal Server Error: Commit cannot be completed since the group has already rebalanced and assigned the partitions to another member_
This means that the time between subsequent calls to poll() was longer than the configured max_poll_interval_ms, which typically implies
that the poll loop is spending too much time message processing_
You can address this either by increasing max_poll_interval_ms or by reducing the maximum size of batches returned in poll() with max_poll_records_”

Tried increasing docker-compose.yml options:

As a result, only deletion the consumer helps, or stopping the container so that the group switches to the empty status.
