I’m getting the following error in LMS container logs, have restarted the container multiple times, restarted docker as well, and installed requirements as well but it doesn’t go away any suggestion?

edx.devstack.master.lms | Exception in thread django-main-thread:

I don’t have any other edx release configured on my local devstack, just juniper.

Hi,
were you able to resolve this issue?

No, it occurs randomly, no permanent solution found so far. I need to restart the respective container more than 1 time till it behaves normally.

The same on Juniper devstack…
