Error `Deserializable entity `GetNearestLocationsResponse` contains unknown properties`

[BBrunekreeft]

When using GetNearestLocations() in BE or DE and no results are found, an exception is thrown. The message is: Deserializable entity 'GetNearestLocationsResponse' contains unknown properties: '['Date','Error','RequestId']'

Example:

$postnl = new PostNL($customer, $apikey, $sandbox);
$result = $postNL->getNearestLocations(
    (new GetNearestLocations())
        ->setCountrycode('DE')
        ->setLocation('70372')
);

This results in the following exception: Deserializable entity 'GetNearestLocationsResponse' contains unknown properties: '['Date','Error','RequestId']' in /var/www/html/test/vendor/firstred/postnl-api-php/src/Entity/AbstractEntity.php:253

The reponse returned by the PostNL API is
