Hello,
This error is raised when I run a migration allowing me to fill in the bd.
To try to resolve the error, I formatted the User object as a *SimpleLazyObject
*because I found that this is the type of object returned by the
*self.request.user* instance in a view.
Here is the model from which I fill the bd and the migration.
Thank you in advance for your solution
