Lighthouse: Nuwave\Lighthouse\Exceptions\DefinitionException : No matching subclass of GraphQL\Type\Definition\ScalarType of found for the scalar Mixed

Created on 19 Mar 2020  路  7Comments  路  Source: nuwave/lighthouse

When trying to execute lighthouse:validate-schema artisan commmand i am getting this error.

Nuwave\Lighthouse\Exceptions\DefinitionException : No matching subclass of GraphQL\Type\Definition\ScalarType of found for the scalar Mixed.

This hasnt ever come up yet and ive been using lighthouse extensively.

I have removed all the contents of my schema.graphql file so it is now a blank file but it is still showing this message.

Expected behavior/Solution
I would execpt the schema to be valid

Steps to reproduce

  1. Install lighthouse
  2. run php artisan validate-schema

@spawnia Actually found out what it was.

There is a bug with the WhereConditionsServiceProvider class. After removing it my graph worked (barring the queries that i had used the experimental where condition on)

After much digging i found out that the way i had installed my packages was all wrong.

mll-lab/graphql-php-scalars

was required by a certain package that we install. however for some reason it wasnt being downloaded at all into the vendor folder probably because of a messed up composer.lock file.

richardabear picture richardabear on 19 Mar 2020

Yeah. I encountered the same problem.
Solved it like this:
In AppServiceProvider class in boot method: 

    $typeRegistry = app(TypeRegistry::class);
    $typeRegistry->register(new MLL\GraphQLScalars\MixedScalar());

The docs explicitly mention that you have to install this package in order for complex where conditions to work:

https://lighthouse-php.com/master/eloquent/complex-where-conditions.html#setup

spawnia picture spawnia on 15 Dec 2020

Just to reiterate, you do need to install that package:

composer require mll-lab/graphql-php-scalars:^4

You also need to add it to config/app.php in the providers section:

'providers' => [
    ...
    \Nuwave\Lighthouse\WhereConditions\WhereConditionsServiceProvider::class,
    ...
],

And as @talismandev mentionned I had to add some code in app/Providers/AppServiceProvider.php except that code had issues with figuring out where things are for some reason so I ended up with:

<?php

namespace App\Providers;

use Nuwave\Lighthouse\Schema\TypeRegistry;
use MLL\GraphQLScalars\MixedScalar;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register()
    {
    }

    /**
     * Bootstrap any application services.
     */
    public function boot()
    {
        $typeRegistry = app(TypeRegistry::class);
        $typeRegistry->register(new MixedScalar());
    }
}

And then, it worked like a charm! Hope it helps
