@Ayushi_Suthar  @Retired_mod I have double-checked and confirmed that the Databricks instance profile is correctly matching with the AWS Instance Profile Name and Role ARN. The trust relationship is also exactly matching with both Databricks workspace IDs. However, I have noticed that while this Databricks instance profile can successfully start a SQL Serverless cluster on us-west-2, it is unable to do so on the ap-southeast-1 workspace.I suspect that this may be due to the recent launch of Serverless on ap-southeast-1. Could this be a bug?
