Pipeline running error for 02c, missing permissions for the service account

[zhhtu]

I'm running the 02c, pipleine.run, and got the following error: "message: "Failed to create pipeline job. Error: Service account [email protected] does not have [storage.objects.get, storage.objects.create] IAM permission(s) to the bucket "learn-demo1". Please either copy the files to the Google Cloud Storage bucket owned by your project, or grant the required IAM permission(s) to the service account..""

It seems the service account does not have permission to the bucket, I've tried to change the role of the account from "Editor" to "owner" manually in the IAM section but it did not work.
