Access denied on this field on query built with PHP way + attributes

[simplis-jourdan]

Hi,

I'm trying to migrate from a YAML implementation to a full PHP implementation.
I well know the solution by using this bundle for years now.
But, with this config, new to me, I'm facing an issue accessing the fields on root query/mutation.

Here's my setup using the 1.7.0.

The graphql:debug does not show the query, but with GraphiQL, it seems to be registered:

And doing this query throws an access error:

I tried to so the same thing on a mutation. Same result.
IsPublic is not supported on providers or queries I guess.

So, at this point, I have no more ideas to find a solution.

Thank you a lot in advance for helping!

@Vincz Pretty sure you're busy but you seem to know well the project, so could you have a look please? :-)
