Brokers Connection string doesn't show creating cIuster with IAM Access

Question

I have created an MSK cluster with IAM Access Control as a mechanism for authentication and authorization. I can see the broker nodes for my cluster on MSK Console but when I try to write a message to a topic from my kafka client, it gives me error "Broker may not be available".  
  
When I used the cli command i.e. get-bootstrap-brokers, it shows no value for the "BootstrapBrokerStringSaslIam". It gives me nothing at all. Not even a message telling the status of brokers.  
  
I have followed the official documentation for it https://docs.aws.amazon.com/msk/latest/developerguide/iam-access-control.html  
  
However, I can get the ZooKeeper string for my IAM Access Control cluster and can create kafka topics from my kafka client.   
  
I don't know what's happened to my brokers.  
  
Can anyone tell me what should I do?

Accepted Answer

I had the same issue when I ran `aws kafka get-bootstrap-brokers` with an out-of-date aws-cli.  Running it with aws-cli/2.2.3 works for me.

Answer

Great tip. You will need to update the version of the CLI to use the latest features when they involve API changes.

Answer

Yes, it is working now. Thank you njlaw and djwylie :)
