Struggling to CreateDBInstanceReadReplica, not working as expected

[bytebeast]

RDS Setup

• foo-2-database-1 # Regional Cluster
  • foo-2-datatase-1-instance-1 # Writer Instance
  • foo-2-database-1-instance-2 # Reader Instance

Code Snippet Failing

	input := &rds.CreateDBInstanceReadReplicaInput{
		SourceDBClusterIdentifier: aws.String(
			"foo-2-database-1",
		),
		DBInstanceIdentifier: aws.String(
			"foo-2-database-1-instance-3",
		),
	}

	result2, err := svc.CreateDBInstanceReadReplica(context.TODO(), input)

The Error

Getting the following error:

panic: Failed to Create DB Instance Read Replica, operation error RDS: CreateDBInstanceReadReplica, https response error StatusCode: 400, RequestID: 50e53a89-d267-4727-b2e9-40ad64659b3a, api error InvalidParameterCombination: Cannot create a read replica for a DB Instance that belongs to a DB Cluster

The profile and region is set correctly because i am able get/print *dbCluster.DBClusterIdentifiler from svc.DescribeDBClusters. Not sure what I'm missing.

I am able to successfully add a read replica via aws console ui.

Figured this out.... was using wrong action call.

Amazon Aurora doesn’t support this action. Call the CreateDBInstance action to create a DB instance for an Aurora DB cluster.
