AttributeError: type object 'User' has no attribute 'DoesNotExist'. Did you mean: '_DoesNotExist'?

It does resolve to a Django attribute through vscode but doesn't seem to work. It's fixed through this. Not sure why no one has run into this yet?

Sorry, missed this.

This fix has to be aware of the fact that this attribute might have a _ or not depending on the state of private-django-api.

Ideally, we're not using this internal Django variable at all. 🤔
