Description
Imagine two classes, both with typed properties and without default values.
First class has an array property of second classes.
Denormalizing into an object with object_to_populate, you could have a case when an array item is being instantiated by the serializer, because it could not be found in the object_to_populate.
In this case with deep_object_to_populate true it will try to read from that freshly instantiated object and fail because typed property is not initialized.
The same case is fixed with normalization: #40578 #41615
How to reproduce
class DataClass
{
public string $unInitialized;
}
$object = new DataClass();
$normalizer = new ObjectNormalizer();
$normalizer->denormalize(
['unInitialized' => 'something'],
DataClass::class,
context: [
'object_to_populate' => $object,
'deep_object_to_populate' => true,
]
);Possible Solution
Make option skip_uninitialized_values work when denormalizing.
