Description

This warning is appearing 30 times during provisioning. It clutters logs and hinders dev experience (https://github.com/openedx/edx-platform/issues/32888).

The warning is being logged here: https://github.com/openedx/XBlock/blob/d28d78b051769520edfa125af1a8e6f989e344ab/xblock/mixins.py#L517

And the root cause should be somewhere in this file: https://github.com/openedx/edx-platform/blob/ff17e51699f1eeed520545f004c29a9572570b01/xmodule/discussion_block.py

AC

  • The warnings stop cluttering logs
