[3.4.3] BC break in Symfony 6.4 - Attempted to call an undefined method named "getSupportedTypes"

[perice]

API Platform version(s) affected: x.y.z
3.4.3 and above

Description
Upgrading from 3.4.2 to 3.4.3 breaks the app because the added ErrorNormalizer wants to call getSupportedTypes() on the inner class which doesn't exist.

Breaks with Symfony 6.4, as the method is not part of the NormalizerInterface:

https://github.com/symfony/symfony/blob/6.4/src/Symfony/Component/Serializer/Normalizer/NormalizerInterface.php

Break caused by adding ErrorNormalizer:

v3.4.2...v3.4.3

How to reproduce
Use Symfony 6.4.*
Use Api Platform 3.4.3+
Not sure - Make it throw an error? or just call getSupportedTypes on something?

Possible Solution
Add getSupportedTypes() to everything that extends the NormalizerInterface
Rewrite the ErrorNormalizer to not call getSupportedTypes() if undefined

I'd like to know the source of the error, does #6825 fixes your issue?

[perice]

Yes, it fixes the issue.

Thanks!
