`Timed out while committing offsets via consumer`

I am trying one test scenario for my kafka stream application,
running single instance of application locally with 2 kafka brokers (setup in docker) the input /output topics have replication factor of 2 and partition 1
When i stop one of the brokers i am getting below exception and application dies
If the other broker is up it still can continue with that… am i missing something?
Timed out while committing offsets via consumer
aused by: org.apache.kafka.common.errors.TimeoutException: Timeout of 60000ms expired before successfully committing offsets

Make sure the internal topics and the consumer offsets topic have a replication factor of 2 as well

Oh i see http://localhost:9021/clusters/WsRZM4v7Tq21u2KG7a4QWw/management/topics/__consumer_offsets/overview|__consumer_offsets topic has 50 partitions and replication and isr is 1
