Custom GraphQL queries not working Cannot query field "fiservGenerateTokenHash" on type "Query"

[glenelkins0624]

I'm just going to show a basic example because nothing works.

I have etc/schema.graphqls with the following example:

type Query{
    fiservGenerateTokenHash: TokenHash @resolver(class: "Vendor\\Module\\GraphQL\\TokenHash")
}

I then have the TokenHash resolver

<?php

namespace Vendor\Module\GraphQL;

use Magento\Framework\GraphQl\Query\ResolverInterface;
use Magento\Framework\GraphQl\Query\Resolver\ContextInterface;
use Magento\Framework\GraphQl\Schema\Type\ResolveInfo;
use Vendor\Module\Service\Encryption as EncryptionService;
use Magento\Framework\GraphQl\Config\Element\Field;

/**
 * Class TokenHash
 * @package Vendor\Module\GraphQL
 */
class TokenHash implements ResolverInterface
{
    /**
     * @param EncryptionService $_encriptionService
     */
    public function __construct(        private readonly EncryptionService $_encriptionService
    )
    {

    }

    /**
     * @param Field $field
     * @param ContextInterface $context
     * @param ResolveInfo $info
     * @param array|null $value
     * @param array|null $args
     * @return array
     */
    public function resolve(Field $field, $context, ResolveInfo $info, array $value =null, array $args = null)
    {
        $tokenHash = $this->_encryptionService->generateNewHashBySessionId();

        return ['token'=>$tokenHash];
    }
}

Now, when i run the basic test in postman to https://mydomain.com/graphql:

query {
    fiservGenerateTokenHash {
        token
    }
}

All i get is this error: Cannot query field "fiservGenerateTokenHash" on type "Query"

This is driving me insane, i can't see anything wrong here

From what I see, your syntax looks correct.

You should verify that you’ve run the cache clearing commands, di-compiler, and set-up your modules.

Or you can get  the Query by this command

curl -X POST \
  https://your-magento-site.com/graphql \
  -H "Content-Type: application/json" \
  -d '{"query": "query { fiservGenerateTokenHash { token } }"}'

It's looking like it's the GraphQL in general, i have the feeling one of the hundreds of modules we use is causing it. It won't be fun debugging this!
