Validation Exception when using master_user_arn

[aws-dev-ops-github-service]

when applying I can see this from the plan

• advanced_security_options {
  + enabled = true
  + internal_user_database_enabled = true

     + master_user_options {
         + master_user_arn = "arn:aws:iam::123456:user/surj@myemail.io"
       }
   }
  

however I get the following error

aws_elasticsearch_domain.es_domain: Creating...

Error: Error creating ElasticSearch domain: ValidationException: You must provide a master username and password when the internal user database is enabled.

@aws-dev-ops-github-service when internal_user_database_enabled is set to true you must provide the username and password.

If you want to use the master_user_arn instead, then set internal_user_database_enabled to false.
