PHP 8.4 deprecates implicitly nullable parameter types. When a typed parameter
has a default value of NULL without an explicit ? prefix on the type hint, PHP 8.4 emits a deprecation warning.
The following notices need to be fixed:
Deprecated: Drupal\reference_value_pair\Plugin\Field\FieldType\ReferenceValuePair::getPossibleValues(): Implicitly marking parameter $account as nullable is deprecated, the explicit nullable type must be used instead in /var/www/html/web/modules/contrib/reference_value_pair/src/Plugin/Field/FieldType/ReferenceValuePair.php on line 473
Deprecated: Drupal\reference_value_pair\Plugin\Field\FieldType\ReferenceValuePair::getPossibleOptions(): Implicitly marking parameter $account as nullable is deprecated, the explicit nullable type must be used instead in /var/www/html/web/modules/contrib/reference_value_pair/src/Plugin/Field/FieldType/ReferenceValuePair.php on line 480
Deprecated: Drupal\reference_value_pair\Plugin\Field\FieldType\ReferenceValuePair::getSettableValues(): Implicitly marking parameter $account as nullable is deprecated, the explicit nullable type must be used instead in /var/www/html/web/modules/contrib/reference_value_pair/src/Plugin/Field/FieldType/ReferenceValuePair.php on line 487

amatzies commentedThis patch works for me using PHP 8.4. The base class EntityReferenceItem changed the signature of these methods in both versions Drupal 11.3 and 10.6 as well.
