Description

Generated stream readers filename depend on the type name:

That means adding or removing a property from an object won’t result in another stream reader being generated, and trying to decode such an object will fail.

This is only an issue in dev env when you will change files without refreshing caches.

How to reproduce

Given a Test class

class Test
{
    public int $id;
}

$test = $reader->read('{"id": 1, "foo": "bar"}', Type::object(Test::class));
dump($test->id);

will correctly display 1.

Now adding a public string $foo property to Test, displaying $test->foo would result in

Typed property Test::$foo must not be accessed before initialization
