Problem/Motivation

On PHP 8.1, when loading a profile programmatically, where the profile's revision data column has a NULL (default) value, the following PHP warning is shown:

Deprecated function: unserialize(): Passing null to parameter #1 ($data) of type string is deprecated in Drupal\Core\Entity\Sql\SqlContentEntityStorage->mapFromStorageRecords()

Steps to reproduce

Load a profile entity where the profile's revision data column has a NULL (default) value, e.g.:

$profile = \Drupal::EntityTypeManager()
    ->getStorage('profile')
    ->loadByUser($user, 'main');

Proposed resolution

Not entirely sure. Should the default value of the data column in the profile_revision table not be NULL?

Hey. After having a look at this one, this is not a Profile module issue, it's a core issue itself.
It's being discussed and worked here: https://www.drupal.org/project/drupal/issues/3300404 📌 Unserialize(): Passing null to parameter #1 ($data) of type string is deprecated in Drupal\Core\Entity\Sql\SqlContentEntityStorage Needs work

There are event patches for that, but they've not been approved yet. I think that #28 is going to do the trick for me at least, despite of I'm aware that it may be a temporary solution.
