const { DescribeClusterCommand, KafkaClient } = require('@aws-sdk/client-kafka')
const cli = new KafkaClient({region: 'us-east-1'})
const command = new DescribeClusterCommand({ClusterArn: '<ARN VALUE>'})
try {
  const response = await cli.send(command)
   console.log()
} catch (error) {
   console.error(error)
}

Observed Behavior

{
  '$metadata': {
    httpStatusCode: 200,
    requestId: '<>',
    extendedRequestId: undefined,
    cfId: '<>',
    attempts: 1,
    totalRetryDelay: 0
  },
  ClusterInfo: {
    ClusterArn: '<>',
    ClusterName: '<>',
    CurrentVersion: '<>',
    EnhancedMonitoring: 'DEFAULT',
    NumberOfBrokerNodes: 3,
    State: 'ACTIVE',
    StorageMode: '<>',
    Tags: { },
    ZookeeperConnectString: '<>',
    ZookeeperConnectStringTls: '<>'
  }
}

Expected Behavior

{
  '$metadata': {
    httpStatusCode: 200,
    requestId: '<>',
    extendedRequestId: undefined,
    cfId: '<>',
    attempts: 1,
    totalRetryDelay: 0
  },
  ClusterInfo: {
    ClusterArn: '<>',
    BrokerNodeGroupInfo : { 
      ClientSubnets: ['']
     },
     ClientAuthentication: {
        Unauthenticated: {
          Enabled: true
        }
     }
    ClusterName: '<>',
    CurrentVersion: '<>',
    EnhancedMonitoring: 'DEFAULT',
    NumberOfBrokerNodes: 3,
    State: 'ACTIVE',
    StorageMode: '<>',
    Tags: { },
    ZookeeperConnectString: '<>',

@pfarkya , Could you use a previous version such as https://www.npmjs.com/package/@aws-sdk/client-kafka/v/3.312.0 while a fix is being worked on?

[kuhe]

A patch was released for this issue in https://www.npmjs.com/package/@aws-sdk/client-kafka/v/3.321.1.

@kuhe Thanks for quick resolution.

I didn't aware about that this file is been generated by codegen. Thanks for new PR.

Should I need to close it or it does an automated stuff.
