On Drupal 8 there is by default a user_picture field for the user's photo. When I started my site several months ago, I deleted this field because I did not use it.
Today I need this field, so I created an image type field.
MY PROBLEM : I installed some modules that use the user's photo, but it can not be found because the user_picture is the default
If I create a user_picture field it automatically adds field_ in front of the machine name.
Is it possible to restore the default field with the correct machine name ?
