Description

The DateTimeNormalizer component throws NotNormalizableValueException if the target class contains the \DateTimeInterface property and json contains Unix timestamp.

PHP Fatal error: Uncaught Symfony\Component\Serializer\Exception\NotNormalizableValueException: The data is either not an string, an empty string, or null; you should pass a string that can be parsed with the passed format or a valid DateTime string. in /home/developer/symfony/serilizer-bug/vendor/symfony/serializer/Exception/NotNormalizableValueException.php:31 Stack trace: #0 /home/developer/symfony/serilizer-bug/vendor/symfony/serializer/Normalizer/DateTimeNormalizer.php(87): Symfony\Component\Serializer\Exception\NotNormalizableValueException::createForUnexpectedDataType() #1 /home/developer/symfony/serilizer-bug/vendor/symfony/serializer/Serializer.php(227): Symfony\Component\Serializer\Normalizer\DateTimeNormalizer->denormalize() #2 /home/developer/symfony/serilizer-bug/vendor/symfony/serializer/Normalizer/AbstractNormalizer.php(432): Symfony\Component\Serializer\Serializer->denormalize() #3 /home/developer/symfony/serilizer-bug/vendor/symfony/serializer/Normalizer/AbstractObjectNormalizer.php(598): Symfony\Component\Serializer\Normalizer\AbstractNormalizer->denormalizeParameter() #4 /home/developer/symfony/serilizer-bug/vendor/symfony/serializer/Normalizer/AbstractNormalizer.php(364): Symfony\Component\Serializer\Normalizer\AbstractObjectNormalizer->denormalizeParameter() #5 /home/developer/symfony/serilizer-bug/vendor/symfony/serializer/Normalizer/AbstractObjectNormalizer.php(244): Symfony\Component\Serializer\Normalizer\AbstractNormalizer->instantiateObject() #6 /home/developer/symfony/serilizer-bug/vendor/symfony/serializer/Normalizer/AbstractObjectNormalizer.php(323): Symfony\Component\Serializer\Normalizer\AbstractObjectNormalizer->instantiateObject() #7 /home/developer/symfony/serilizer-bug/vendor/symfony/serializer/Serializer.php(227): Symfony\Component\Serializer\Normalizer\AbstractObjectNormalizer->denormalize() #8 /home/developer/symfony/serilizer-bug/vendor/symfony/serializer/Serializer.php(145): Symfony\Component\Serializer\Serializer->denormalize() #9 /home/developer/symfony/serilizer-bug/serilizer-bug.php(44): Symfony\Component\Serializer\Serializer->deserialize() #10 {main} thrown in /home/developer/symfony/serilizer-bug/vendor/symfony/serializer/Exception/NotNormalizableValueException.php on line 31
