Can't set a scalar parameter with GraphQL services

Hi and thanks for your work !

I think I have encountered a bug in the compiler pass of the bundle. I can't manage to use named parameter with autowiring for my GraphQL services, they are reset somehow.

Reproduction

in services.yaml

    App\GraphQL\Mutation\UploadMutation:
        arguments:
            $cardUploadDir: '%card_upload_dir%'

in App\GraphQL\Mutation\UploadMutation

class UploadMutation implements MutationInterface, AliasedInterface
{
    private $cardUploadDir;

    public function __construct(string $cardUploadDir)

I always end up with the exception

Cannot autowire service "App\GraphQL\Mutation\UploadMutation": argument "$cardUploadDir" of method "__construct()" is type-hinted "string", you should configure its value explicitly.

Temporary fix for me

Quick and dirty fix for me was to override the process function in my kernel.

    public function process(ContainerBuilder $container)
    {
        $container->getDefinition('App\GraphQL\Mutation\UploadMutation')->setArgument('$cardUploadDir', '%card_upload_dir%');
    }

Hi! thanks for reporting this issue and the reproduction. We'll try to give this a fix quickly.

Ok I get it, your service is missing the mutation tag

    App\GraphQL\Mutation\UploadMutation:
        arguments:
            $cardUploadDir: '%card_upload_dir%'
        tags: ['overblog_graphql.mutation']

I'm having the same issue with the tag sadly.

Can you try to remove MutationInterface

[tlenclos]

I'm having a weird exception now with

class UploadMutation implements AliasedInterface
{

    App\GraphQL\Mutation\UploadMutation:
        tags: ['overblog_graphql.mutation']
        arguments:
            $cardUploadDir: '%card_upload_dir%'

Hi, what's the status on this bug? I'm using your package and I need to pass entity manager with alternative connection. I'm doing this from services.yaml

        AppBundle\GraphQL\Mutation\UserMutation:
              tags: ['@overblog_graphql.mutation']
              arguments:
                  $em: '@doctrine.orm.user_entity_manager'

And when I autowire argument in class __constuct, I get default entity manager.

This bug was not fixed since this could introduce BC, this come from AliasedInterface usage, removed it and defined your aliases using tags.

Thanx for quick answer, but it did not help:( I'll post my whole code, please look at it, maybe I've made a mistake somewhere.

mutation class:

Class UserMutation implements MutationInterface
{
    /**
     * @var EntityManagerInterface
     */
    protected $em;

    public function __construct(EntityManagerInterface $em)
    {
        \Doctrine\Common\Util\Debug::dump($em->getConnection());die; // here I get default connection
        $this->em = $em;
    }

    public function createUser(array $args): User
    {...}
}

services.yaml

AppBundle\GraphQL\Mutation\UserMutation:
        arguments:
            $em: '@doctrine.orm.user_entity_manager'
        tags: 
            - { name: overblog_graphql.mutation, method: createUser, alias: createUser }

Mutation.yaml

Mutation:
    type: object
    config:
        fields:
            createUser:
                type: User!
                resolve: '@=mutation("AppBundle\\GraphQL\\Mutation\\UserMutation::createUser", [args["input"]])'
                args:
                    input:
                        type: UserInput!

if you want to use fqcn you must remove alias:

AppBundle\GraphQL\Mutation\UserMutation:
        arguments:
            $em: '@doctrine.orm.user_entity_manager'
        tags: 
            - { name: overblog_graphql.mutation, method: createUser }

[Sephirothus]

Did not helped, still default connection:( Any thoughts?

[mcg-web]

Do you have some wildcard rules in your dependency injection configuration?

[Sephirothus]

I get a quick look at project and not found any wildcards

[mcg-web]

Can you name your service

app.user_mutation:
        class: AppBundle\GraphQL\Mutation\UserMutation:
        arguments:
            $em: '@doctrine.orm.user_entity_manager'
        tags: 
            - { name: overblog_graphql.mutation, method: createUser }

what is the output of this CLI?

bin/console graphql:debug --category=mutation

[Sephirothus]

solution id: AppBundle\GraphQL\Mutation\UserMutation::createUser
app.user_mutation::createUser aliases :

It's shown in table, but I don't know how to visualise table, sorry:)
