Hi,

😅 I missed these dependencies.
They are also needed in MetadataStatementSerializerFactory.

[joostdebruijn]

@Spomky Thanks for merging this one! However, the web-auth/webauthn-lib sub repository doesn't have the Symfony serializer related packages now (also not in the suggest)? I'm using that sub repo for my own implementation in the Laravel-framework, however the three Symfony serializer related packages are necessary for parsing the authenticator responses for example. Shouldn't they be added as suggested package at least?

[Spomky]

No worries, it is automatically split and tagged on release

[joostdebruijn]

@Spomky Hm, I'm using v4.8.1 now and when only requiring web-auth/webauthn-lib, the symfony serializer packages must be installed separately.

The package phpdocumentor/reflection-docblock should be added as dependency well as I discovered in production where my dev dependencies are not installed. 😅
