Confluent community confluentinc/cp-kafka:7.0.1 giving ClassNotFoundException:io.confluent.metrics.reporter.ConfluentMetricsReporter

[glitch-k8s]

Objective: I am trying to install Confluent kafka community version using Helm command (Helm version 3). Enterprise image is working successfully.

Command : helm install my-kafka confluentinc/cp-helm-charts --set cp-schema-registry.enabled=false,cp-kafka-rest.enabled=false,cp-kafka-connect.enabled=false,cp-ksql-server.enabled=false,cp-control-center.enabled=false --set cp-zookeeper.imageTag=7.0.1,cp-zookeeper.persistence.enabled=false --set cp-kafka.persistence.enabled=false,cp-kafka.prometheus.jmx.enabled=false --set cp-kafka.image=confluentinc/cp-kafka,cp-kafka.imageTag=7.0.1,cp-kafka.nodeport.enabled=true,cp-kafka.configurationOverrides.CONFLUENT_SUPPORT_METRICS_ENABLE=false

Output:
