These are the steps I followed:

1) Under quickstart-> added workspace name-> selected N-virginia (us-east-1), and quick start

2) next step: except the password, I haven't edited any of the below:

stackname- (default) databricks-workspace-stack

parameters like- account email address, IAM role and S3 bucket conf

3) then I get rollback error

*Note my AWS console region shows N-virginia(us east1), hence I selected that during the quickstart page

Please let me know how to resolve it, is there any role to be added or any change in the parameter to be made

I followed all the steps as per this: https://docs.databricks.com/getting-started/account-setup.html

Attached errors as well
