1. accessKeyId
2. secretKey
3. host
4. clientId
5. region
6. sessionToken

My client has been created successfully, and my connect event is working fine but before message event is called, I get an error of connection close like this

Please provide full, minimal standalone repro. The code snippet is insufficient.

In general, a reliable connection closed behavior is usually due to incorrect permissions on the IAM policy that is associated with the credentials used to establish the websocket connection. What is the policy you are using?
