I've tried using the workgroup endpoint, and Redshift-managed VPC endpoints, but get the error message:
Cluster 'XXXXX' does not exist.
Does that seem like a VPC issue, or is there a quirk re Redshift Serverless? Anyone using this combo?
From what it seems DMS doesn't support Redshift serverless yet: https://repost.aws/questions/QUxMagDflyR1O9TpjLE7fjxg/how-to-create-dms-migration-endpoint-for-redshift-serverless
