Unable to populate one to many relationship data

I have two collection course and session and i have added a relation field in the course collection having one to many relationship, field name I have used is sessions in course collection.
When I am trying to grab the sessions for each course using populate its not returning in the api response. whereas data is getting populated fine for the component relations I have with course collection.

If anyone can help with this that will be very helpful for me.

Thanks!

<@239104470137569283> any ideas here, looks like it should work to me, gone over it in office hours - the component populates fine, but the relation does not. No obvious errors, nothing noticable as “incorrect implementation” - asked Rajat to come to tonights open office hours
