I think you didn't update the USERNAME Field in your model. If you want to use email as a username you must change the USERNAME field.

Djoser uses the get_user_model method to get the User model of the project so after that it uses the field called USERNAME_FIELD from the model like below.

new_username = serializer.data["new_" + User.USERNAME_FIELD]

So this time I saw your data is new_email and djoser is looking for new_username. To fix this

class User(...):
  ....
  ...
  USERNAME_FIELD = 'email'
  

After that, it will be fixed hopefully.
