Since #35235
SerializerInterface::deserialize()
andDenormalizerInterface::denormalize()
return types are no longer correct.I suggest using
mixed
to allow custom denormalizers to denormalize to any type. For instance, I might addClosureDenormalizer
orNullDenormalizer
orResourceDenormalizer
, technically there are no limits.
