Add a more helpful error message to "projects.jobs.create"
I'm trying to launch a batch pipeline from outside the project and the "projects.jobs.create" API is returning:
"message": "Request contains an invalid argument.",
With no indication on which argument is invalid. This wouldn't be such a big deal, except that the documentation for this (https://cloud.google.com/dataflow/docs/reference/rest/v1b3/projects.jobs/create?authuser=1) does not indicate which fields are required. :(
