Kafka consumer group script to see all consumer group not working

Question

When I execute the below command in kafka

./kafka-consumer-groups.sh --bootstrap-server sample-address:9092 --list

I'm facing the below error

In my case I noticed that we were using SSL

listeners=SSL://sample-address:9092

so I figured that I need to pass SSL properties in the command and it worked

bin/kafka-consumer-groups.sh --bootstrap-server sample-address:9092 --list --command-config /kafka/config/client-ssl.properties

client-ssl.properties

bootstrap.servers=sample-address:9092
security.protocol=SSL
ssl.truststore.location=/keys/truststore.jks
ssl.truststore.password=*****
ssl.keystore.location=/keys/keystore.jks
ssl.keystore.password=*****
