Unable to get Broker metrics - KafkaBrokerSample - Kafka Integration

This is my config file snippet:

  • name: kafka-metrics-bootstrap-discovery
    command: metrics
    arguments:
    cluster_name: “npcluster1”
    autodiscover_strategy: “bootstrap”
    bootstrap_broker_host: “”
    bootstrap_broker_kafka_port: 9092
    bootstrap_broker_kafka_protocol: SSL
    bootstrap_broker_jmx_port: 9999
    tls_cert_file: /app/kafka/keystore/iaas.crt
    tls_key_file: /app/kafka/keystore/iaas.key
    tls_ca_file: /app/kafka/keystore/DigiCertCA.crt
    tls_insecure_skip_verify: true
    collect_broker_topic_data: true
    topic_mode: ‘all’
    labels:
    env: NONPROD
    role: Kafka-NP-Broker

    • name: kafka-inventory
      command: inventory
      arguments:
      cluster_name: “npcluster1”
      autodiscover_strategy: “bootstrap”
      bootstrap_broker_host: “”
      bootstrap_broker_kafka_port: 9092
      bootstrap_broker_kafka_protocol: SSL
      bootstrap_broker_jmx_port: 9999
      topic_mode: ‘all’
      collect_broker_topic_data: true
      tls_cert_file: /app/kafka/keystore/iaas.crt
      tls_key_file: /app/kafka/keystore/iaas.key
      tls_ca_file: /app/kafka/keystore/DigiCertCA.crt
      tls_insecure_skip_verify: true
      labels:
      env: NONPROD
      role: Kafka-NP-Broker

Basically I am unable to get the Broker Metrics in NR insights. I tested the jmx connectivity with the help of JMX tool and I see the metrics. See below -

bin/kafka-run-class.sh kafka.tools.JmxTool --object-name kafka.server:type=BrokerTopicMetrics,name=MessagesInPerSec
Trying to connect to JMX url: service:jmx:rmi:///jndi/rmi://:9999/jmxrmi.

The error I get in nr log file -
