 Skipping uninitialized properties
 ---------------------------------

 PHP 7.4 introduced typed properties, which have a new state - ``uninitialized``.
 This is different from the default ``null`` of untyped properties.
 When you try to access it before giving it an explicit value - you get an error.

 By default, to avoid the Serializer throwing an error when serializing or normalizing an object with
 uninitialized properties, object normalizer catches these errors and ignores such properties.

 You can disable this behavior by setting the ``AbstractObjectNormalizer::SKIP_UNINITIALIZED_VALUES`` context option to ``false``::

    class Dummy {
        public string $foo = 'initialized';
        public string $bar; // uninitialized
    }

    $normalizer = new ObjectNormalizer();
    $result = $normalizer->normalize(new Dummy(), 'json', [AbstractObjectNormalizer::SKIP_UNINITIALIZED_VALUES => false]);
    // throws Symfony\Component\PropertyAccess\Exception\UninitializedPropertyException as normalizer cannot read uninitialized properties

 .. note::

    Calling ``PropertyNormalizer::normalize`` or ``GetSetMethodNormalizer::normalize`` with ``AbstractObjectNormalizer::SKIP_UNINITIALIZED_VALUES`` context option set to ``false`` will throw an ``\Error`` instance if the given object has uninitialized properties as the normalizer cannot read them (directly or via getter/isser methods).

 .. versionadded:: 5.4

    The ``AbstractObjectNormalizer::SKIP_UNINITIALIZED_VALUES`` constant was introduced in Symfony 5.4.
