• DBcluster name : cluster-name
• DbInstance class : db.t2.small
• DB Instance Identifier : testdbinstance
• Engine : aurora

it gives the below error:

The requested DB Instance will be a member of a DB Cluster. Enable or disable IAM database authentication for the DB Cluster. (Service: AmazonRDS; Status Code: 400; Error Code: InvalidParameterCombination; Request ID: e2ccfd13-f684-400f-b83f-52943bea854b)

but while i creating i set IAM Database Authentication to false.

Answer 1

What helped me:

I have both aws rds restore-db-cluster-from-snapshot and aws rds create-db-instance with option --no-enable-iam-database-authentication. I removed this option from aws rds create-db-instance and it helped
