[GraphQL] Error with custom Filters

[toitzi]

API Platform version(s) affected: 4.0.4

Description
I have a strange bug, which i am not Sure is Laravel unique, or an API-Platform issue or a graphql-php issue. To reproduce you should have the following setup:

• Laravel API-Platform with graphql enabled
• A Model with custom graphqlOperations, one of it beeing a custom parameter for a query collection (orderFilter - provided with this package):

I have applied those to my model called "Tenant". If i now visit the /api/graphql endpoint of my application to test it out, i can try that query:

( This query is schematically correct, and validated correctly by the UI)

However this will give me the following "funny" error, saying that "orderTenantcollection_query" is not a known type, and if i meant "orderTenantcollection_query" (the same lol):

To check why i checked the KnownTypeNames.php file of the graphql-php library. There is a check for $schema !== null && $schema->hasType($typeName) which resolves to false hence generating the error. However to generate the error message graphql-php get's a list of all possible types by calling $schema->getTypeMap() which will fully load all types (According to the function documentation this is not for production use since it does a full schema scan) and "orderTenantcollection_query" will be included there. A check for $schema !== null && $schema->hasType($typeName) after this would resolve to true then.

I have no idea, why graphql-php does not try again after a full scan (possibly performance issues) or where the exact problem lies here - hence i do not know how to fix it. (maybe api-platform uses / can use a typeLoader in the schema class, maybe something else does need to be specified). Maybe someone here with more insight knows what the problem is.

Mhh indeed this is a hard problem read more at: https://github.com/api-platform/core/blob/main/src/GraphQl/Type/FieldsBuilder.php#L293-L301

If you find a way to fix this in a quick and dirty (opposed to the multi days refactor this comments refer to) manner I'm definitely up for it!
