CSV file that lists all student answers to the problem

Open edX
1

As I followed the steps to download CSV of problem responses for a problem, It says “The problem responses report is being created. To view the status of the report, see Pending Tasks below.”
But, I am not seeing any pending tasks nor the files are being generated. Can’t see the generated file even after refreshing.
But, I can generate other CSV files for example, Problem Grade Report.
The issue is only for the problem response report.

PS: When I checked Admin, I could see that the request was failed with this error:
{"exception": "AssertionError", "traceback": "Traceback (most recent call last):\n File \"/openedx/venv/local/lib/python2.7/site-packages/celery/app/trace.py\", line 240, in trace_task\n R = retval = fun(*args, **kwargs)\n File \"/openedx/venv/local/lib/python2.7/site-packages/celery/app/trace.py\", line 438, in __protected_call__\n return self.run(*args, **kwargs)\n File \"/openedx/edx-platform/lms/djangoapps/instructor_task/tasks.py\", line 171, in calculate_problem_responses_csv\n return run_main_task(entry_id, task_fn, action_name)\n File \"/openedx/edx-platform/lms/djangoapps/instructor_task/tasks_helper/runner.py\", line 111, in run_main_task\n task_progress = task_fcn(entry_id, course_id, task_input, action_name)\n File \"/openedx/edx-platform/lms/djangoapps/instructor_task/tasks_helper/grades.py\", line 737, in generate\n usage_key_str=problem_location\n File \"/openedx/edx-platform/lms/djangoapps/instructor_task/tasks_helper/grades.py\", line 674, ...", "message": ""}

Please help.

@regis
Will you be able to look into this issue for me?

Thanks

Unfortunately I cannot reproduce this issue. Any chance you can find a more complete stacktrace? The error logs can be found by running tutor local logs lms-worker right after triggering the error.

Thanks @regis for it.

Here is the log after triggering that error.

Did you modify one of the problems after some of the students answered it? That makes it impossible to grade the problem. Unfortunately I don’t have time to help you with that.

@regis
That’s what happened.
Thank You for your valuable time for helping me catch the problem.
If you can spare a few minutes, please give me some hints, no need to get me to the solution. I’ll just figure my way out with that.

Thanks again
