I am getting same error in all labs which requires to submit jobs on dataflow. I am able to run with DirectRunner. Please help in this as I have spent too many hours but end up getting same error again and again

My conclusion from this lab is that I should not use or depend on this type of platform for production loads. It if does not even work in a controlled lab, then production is a no-go!

This is likely a quota issue or a Compute Engine stockout. The service will retry.

Try a different zone, or try again later.

In the Python script, allow users to pass alternative machine types, so there is no possibility of being unable to complete the lab due to insufficient resources being available (for N1?)

There is currently an issue with google.auth library (https://github.com/googleapis/google-cloud-python/issues/16090) that prevents me from finishing the lab - took a long time to find the root couse and I run out of time. Additionally, the worker zones and machine types have to be specified because without them the dataflow cannot spawn workers and jobs keep failing.
