Dataflow setting Controller Service Account

I try to set up controller service account for Dataflow. In my dataflow options I have:

options.setGcpCredential(GoogleCredentials.fromStream(new FileInputStream("key.json")).createScoped(someArrays)); 
options.setServiceAccount("xxx@yyy.iam.gserviceaccount.com");

But I'm getting:

WARNING: Request failed with code 403, performed 0 retries due to IOExceptions, performed 0 retries due to unsuccessful status codes, HTTP framework says request can be retried, (caller responsible for retrying): https://dataflow.googleapis.com/v1b3/projects/MYPROJECT/locations/MYLOCATION/jobs

}

Am I missing some Roles or permissions?
