How to enable Google Classroom courseWorkList

Question

I've been testing the Google Classroom Api and can't seem to get the courseWorkList method to run getting a caller error

I've basically cut and pasted code from the reference and it works if i remove the classCourseWork line. Otherwise I get a "The caller does not have permission" error. I've enabled the API services, approved it to run, etc. Any help in getting this one sorted?

 function listCourses() {
  var optionalArgs = {
    pageSize: 10
  };
  var response = Classroom.Courses.list(optionalArgs);
  var courses = response.courses;

  if (courses && courses.length > 0) {
    for (i = 0; i < courses.length; i++) {
      var course = courses[i];
        var classCourseWork = Classroom.Courses.CourseWork.list(course.id);
      }
      Logger.log('%s (%s)', course.name, course.id);

  } else {
    Logger.log('No courses found.');
  }
}

I've tried your code, here are the scenarios:

As a student:

Your code is working fine.

As a teacher:

I've also received "The caller does not have permission" error.

You might want to check this open issue tracker, that a teacher cannot access the coursework (or the students' turned-in assignments) in their course, getting the same permission error. It was updated and was filed a ticket internally, we can follow this ticket to be updated.

Hope this helps.
