Bug report?	yes
Feature request?	no
BC Break report?	might be
RFC?	?
Version/Branch	0.14.1

Reproduction

• Follow the instructions in Annotations (see code below)
• Open GraphiQl

Expected

• GraphiQL does open
• Query Schema of Graph to be possible

Experienced

• InvalidConfigurationException: The path "overblog_graphql_types.RootQuery._object_config.fields" should have at least 1 element(s) defined.

Code

/config/packages/graphql.yaml

overblog_graphql:
  definitions:
    schema:
      query: RootQuery
    mappings:
      types:
        - type: attribute
          dir: "%kernel.project_dir%/src/GraphQL"
          suffix: ~

/config/bundles.php

    // ...
    Overblog\GraphQLBundle\OverblogGraphQLBundle::class => ['all' => true],
    Overblog\GraphiQLBundle\OverblogGraphiQLBundle::class => ['dev' => true],

/config/services.yaml

// ...
com\our_namespace\api\v2\GraphQL\RootQuery:
    public: true

/src/GraphQL/RootQuery.php

<?php declare(strict_types=1);

namespace com\our_namespace\GraphQL;

use Overblog\GraphQLBundle\Annotation as GQL;

#[GQL\Type]
class RootQuery
{
    // empty as it is in the docs
}

/src/GraphQL/TestType.php

<?php declare(strict_types=1);

namespace com\our_namespace\api\v2\GraphQL\;

use Overblog\GraphQLBundle\Annotation as GQL;

#[GQL\Type]
class TestType
{
    #[GQL\Field(type: "Int")]
    public $myField = 1;
}

Further Information

• If we add Test type explicitly to the RootQuery as an attributed property everything works out
• While debugging we saw that the ConfigParserPass does find the TestType as well as the RootQuery. Nevertheless it does not seem to merge or apply the found TestType to the RootQuery.

Maybe this is not a bug but simply misunderstanding or misleading docs. We appreciate every kind of help here.

[Bastianowicz]

Well it was definitely our issue not yours. We were being helped in the symfony devs channel. The Problem for us was that we had not yet defined any providers and thus no types were being merged in the RootQuery. So what finally helped us was the following snippet. Something comparable would've helped us in the docs but maybe we just followed the wrong path.

#[GQL\Provider]
class MeResolver implements QueryInterface
{
    public function __construct(private TokenStorageInterface $tokenStorage)
    {
    }

    #[GQL\Query(name: 'me', type: 'User')]
    public function __invoke(): ?User
    {
        return $this->tokenStorage->getToken()?->getUser();
    }
}

I get same error and no solution work. I guess doc should be updated to be easily use with php attributes or annotations.
