The following code throws an error under version 3.31.0 but not under 3.30.0:

class Foo
{
    public float|int|null $a = 99;
}

$serializer = SerializerBuilder::create()->build();
$serializer->serialize(new Foo(), 'json');

The error is:

In Parser.php line 30:                                                                                       
JMS\Serializer\Type\Parser::parse(): Return value must be of type array, null returned

Thank you @scyzoryck

Do you believe it is a quick error to fix, or will it take a long time?
