Hi all! Has anyone encountered such an error?

The consumer reads data from Kafka (version 6.0 from confluent). From time to time the following errors occur:
-Error sending fetch request
-Group coordinator (id: <> rack: null) is unavailable or invalid, will attempt rediscovery

Found an unresolved issue here: [KAFKA-7697] Possible deadlock in kafka.cluster.Partition - ASF JIRA

The error is not permanent. A couple of days may not be, and then several times in a row. Here it is advised to set a broker_id, but it already exists ( java - The group coordinator is not available-Kafka - Stack Overflow ).
max.records.per.poll, but it’s already 1.
