[BUG] TYPO3 12: AbstractUuidAwareObjectTypeConverter::setParentObjectAndProperty: "Return value must be of type mixed, none returned" exception

[3l73]

The abstract class AbstractUuidAwareObjectTypeConverter implements the PimBasedTypeConverterInterface.
The method setParentObjectAndProperty() should as defined in the interface return mixed data.
However, the method returns nothing which leads into the exception "Return value must be of type mixed, none returned"

Expected behaviour

Call of the method setParentObjectAndProperty() does not lead to an exception

To Reproduce

1. Call the method setParentObjectAndProperty() within your code.

Used versions:
TYPO3: v12.4.17
Extension version: 3e00a60 (@Dev-Master)

Additional context

The interface PimBasedTypeConverterInterface defines the method setParentObjectAndProperty() with the return type mixed.

crossmedia_fourallportal/Classes/TypeConverter/PimBasedTypeConverterInterface.php

Line 18 in 3e00a60

public function setParentObjectAndProperty(AbstractEntity $object, string $propertyName): mixed;

The abstract class AbstractUuidAwareObjectTypeConverter which implements the function defines the correct return type but does not return anything.

crossmedia_fourallportal/Classes/TypeConverter/AbstractUuidAwareObjectTypeConverter.php

Line 47 in 3e00a60

public function setParentObjectAndProperty(AbstractEntity $object, string $propertyName): mixed

Since a setter normally don't have to return anything, the return type should be changed to void, or if a return value is required, the method should return the correct value.
