Ok, so the error message is rather straight-forward and explains the cause of the problem.

Is there a question you’re looking to have answered?

Note: Please read How do I ask a good question? - Help Center - Stack Overflow

3

Yes. Previously I tried with django’s built-in User model inside the Profile model.
and extended it with OneToOneField.
but when I extended User with with CustomUser now it breaks.
Don’t know how to fix it.
And why is it happening?

4

What is the error message telling you is wrong?

And, have you read How do I ask a good question? - Help Center - Stack Overflow yet?

5

Yes I’ve read the stack overflow how do I ask a good question.
And the hint I’m getting is my Profile object is not getting created from the signal.
But don’t know how to fix it

6

I also updated it to Profile.objects.create(user=instance)

7

fixed the error in my settings.
I was manually calling ‘users’ instead of ‘users.apps.UsersConfig’
and for that reason signals.py wasn’t imported.
because it was imported apps.py
