laravel-json-api: Auth middleware raising unresolvable dependency on Api class

Hello guys!

For authentication I’m using tymondesigns/jwt-auth integrated with Laravel Passport classes, without using HTML boilerplate, of course, because it is an API.

So I have the following code registering routes in my routes/api.php:

app('json-api')->register('v1', [], function (ApiGroup $api, $router) {
    $router->group([
        'prefix' => 'auth',
        'as' => 'auth.',
    ], function ($router) {
        $router->post('login', 'AuthController@login')->name('login');
        $router->post('logout', 'AuthController@logout')->name('logout');
        ...
    });

    $router->group([
        'middleware' => ['auth'],
    ], function () use ($api, $router) {
        $api->resource('first-resource');
        $api->resource('second-resource');
        ...
    });
});

In my AuthController on __construct method I used $this->middleware('auth', 'except' => ['login']); and everything is working fine. Login is not protected and logout requires authentication. Notice that I’m using default Laravel router ($router) to define the routes.

However while protecting resources by creating a router group with middleware auth, when unauthenticated, the API is returning two errors:

1. A correctly unauthenticated error from auth middleware formated in JSON:API:

{
    "errors": [
        {
            "status": "401",
            "title": "Unauthenticated"
        }
    ]
}

1. An unresolvable dependency in JSON format:

            "type": "->"
        },
        {
            "file": "...server.php",
            "line": 19,
            "function": "require_once"
        }
    ]
}

In case of an authentication is provided (a JWT through Bearer) everything works fine and the data is returned.

I had already tried to not use groups and:

1. Use 'middleware' => 'auth' option in each resource.
2. Extend controller by using 'controller' => 'ApiController' and then using $this->middleware('auth') inside controller’s construct method.
3. Re-register the v1 API using 'middleware' => 'auth' option in second parameter of register function.

None of them worked and always these two errors are thrown to the user. Is this a bug or may I’m missing something?

BTW I’m using dev-develop branch that was installed using reference 63095e737a5523ee64aefed901ed64a6623629ce

Thanks in advance!
