The issue was that the assignment was created by the google classroom UI rather than my python code. Google doesn't allow you to modify the grade of any assignment that isn't directly associated with you. If you run this code and get a permission error, you won't be able to update the grade.

coursework = service.courses().courseWork().get(
    courseId=course_id, 
    id=coursework_id
).execute()

if not coursework.get('associatedWithDeveloper'):
    raise PermissionError("Resource owned by Google's internal project")
else:
    print("This is associated with you!")
