Unsupported driver [mongodb]

[saurabhrc15]

I'm currently working with PHP (v8.1), Laravel/Lumen Framework (^10.0), MongoDB (v7.0.2), mongodb/laravel-mongodb(^4.0), mongodb/mongodb(^1.16) and Linux (v20.04). I've successfully installed the PHP MongoDB extension. I verified its installation for the CLI using the command php -m | grep mongodb, which returned "mongodb". Additionally, through phpinfo(), I confirmed that the MongoDB extension is enabled in the Apache web server.

For the Laravel-Lumen setup, I've learned that one should register MongoDB\Laravel\MongoDBServiceProvider::class before invoking $app->withEloquent(). However, when I attempt this, I encounter an error: "Call to a member function prepare() on null". Furthermore, a recurrent error I face states "Unsupported driver [mongodb]". I'm puzzled by these issues. Can someone shed some light on them and assist me?

bootstrap/app.php

<?php

require_once __DIR__.'/../vendor/autoload.php';

(new Laravel\Lumen\Bootstrap\LoadEnvironmentVariables(
    dirname(__DIR__)
))->bootstrap();

date_default_timezone_set(env('APP_TIMEZONE', 'UTC'));

$app = new Laravel\Lumen\Application(
    dirname(__DIR__)
);

$app->singleton(
    Illuminate\Contracts\Debug\ExceptionHandler::class,
    App\Exceptions\Handler::class
);

$app->singleton(
    Illuminate\Contracts\Console\Kernel::class,
    App\Console\Kernel::class
);

$app->configure('jwt');
$app->configure('api');
$app->configure('database');

$app->withFacades();
$app->withEloquent();

$app->middleware([
]);

$app->routeMiddleware([
]);

$app->register(App\Providers\AuthServiceProvider::class);
$app->register(Tymon\JWTAuth\Providers\LumenServiceProvider::class);
$app->register(App\Providers\DatabaseServiceProvider::class);
$app->register(MongoDB\Laravel\MongoDBServiceProvider::class);

$app->router->group([
    'namespace' => 'App\Http\Controllers',
], function ($router) {
    require __DIR__.'/../routes/web.php';
});

return $app;

same bug, need fix

[zyz954489346]

I found the cause of the problem.
See this Provider:

If there is a package run "app('db')" or "app->make('db)" in its provider, before this code in laravel-mongodb package.
Because db is registered as a singleton，so the resolving function will not be executed again.
So mongodb cannot be properly bound to the Provider.

[zyz954489346]

In the final analysis, it is because mongo is registered through resolving rather than through the make function.
This may be a BUG, but it's not clear why need to regist by resolving instead of make.

Hi, thanks for finding this - do you have any suggestions about how to resolve it?

I've explained the issue here: #2715 (comment)

I temporarily solved the problem by modifying the loading order of providers in config/app.php, but this is only a temporary solution.

Here example:

'providers' => ServiceProvider::defaultProviders()->merge([

        // Ensure that conflicting packages load first
        Mnabialek\LaravelSqlLogger\Providers\ServiceProvider::class,

        // Application Service Providers
        App\Providers\AppServiceProvider::class
        // ...etc

    ])->toArray(),
