xqueue is not working

[vthily]

Description:

Xqueue is not working.

• Xqueue plugin is enabled and configured in LMS.
• When user submit the code, it should be delivered and pushed to the database.
• Xqueue-watcher (external grader) will pull the code from the database, grade, and return the result to the LMS.

Expected behavior:

With correct queue name, and configure for xqueue-watcher, user should able to submit the code, seeing the result (pass or fail).

Actual behavior:

When submit the the code, user got the error message:
Unable to deliver your submission to grader (Reason: login_required). Please try again later.

Other notes:

• It was working with Python course in Spring 2021
• Using edx-platform code from branch open-release/gotit.master (search for keyword XQueueInterface)
  common/lib/capa/capa/xqueue_interface.py
• Using lms-infrastructure repo to build the image, change/update the configuration in configmaps. Link
• Use overhang-tutor to deploy.
• xqueue: https://github.com/overhangio/tutor-xqueue (image: overhangio/openedx-xqueue:11.0.0)
