Method MagicSunday\JsonMapper::makeInstance() has parameter $constructorArguments with no value type specified in iterable type array.

Method MagicSunday\JsonMapper::getReflectionClass() never returns null so it can be removed from the return type.

Dead catch - ReflectionException is never thrown in the try block.

Variable method call on object.

Call to function method_exists() with Symfony\Component\PropertyInfo\Type and 'getCollectionValueT…' will always evaluate to true.

Call to deprecated method getCollectionValueType() of class Symfony\Component\PropertyInfo\Type: since Symfony 5.3, use "getCollectionValueTypes()" instead
