After a couple of search, i found that with juniper we have to generate lms_user_id or allow this option to be ignored, according to this:

I dont exactly know how to do it:

1- Enabling the allow_missing_lms_user_id waffle switch : don’t clearly know how to do it :sweat:

2- The LMS user id can be back-filled for existing users by running the ecommerce/core/management/commands/ management command : even running this command, how do i do it?

And, what is the good option, 1- enabling the waffle switch or 2- back-filled for existing users ?


I think you have only one option now to run the management command which back fills LMS user ids for existing users like this

sudo su ecommerce -s /bin/bash
cd ~/ecommerce
source ../ecommerce_env
python import_user_ids --settings=ecommerce.settings.production
