Hi @FlukeStarbucker ,

could you ensure that AM role databricks-workspace-stack-XXXf3-role has the necessary permissions to pass the role ec2-dbricks?

Do you see something like below in your IAM policy?

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "iam:PassRole",
      "Resource": "arn:aws:iam::5249XXXXXXXX:role/ec2-dbricks"
    }
  ]
}
