Laravel - Target [App\Interfaces\Auth\AuthInterface] is not instantiable while building - laravel

Question

In my Laravel-8 application, I am trying to bind Repository to an Interface
I have this code:
App\Providers\RepositoryServiceProvider:
class RepositoryServiceProvider extends ServiceProvider
{
public function register()
{
$this->app->bind(
'App\Interfaces\Auth\AuthInterface',
'App\Repositories\Auth\AuthRepository'
);
}
}
config\app:
App\Providers\RepositoryServiceProvider::class,
Then the interface looks like this:
namespace App\Interfaces\Auth;
use Illuminate\Http\Request;
use App\Http\Requests;
interface AuthInterface
{
public function register(Request $request);
}
Repository Implementation:
namespace App\Repositories\Auth;
use App\Interfaces\Auth\AuthInterface;
use App\Models\User;
use Illuminate\Support\Facades\Auth;
use App\Traits\ApiResponse;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Password;
use Carbon\Carbon;
use Illuminate\Support\Facades\DB;
class AuthRepository implements AuthInterface
{
use ApiResponse;
public function register(DriverRequest $request)
{
DB::beginTransaction();
try {
$newUser = User::create([
'first_name' => $request->first_name,
'last_name' => $request->last_name,
'email' => preg_replace('/\s+/', '', strtolower($request->email)),
'password' => bcrypt($request->password)
]);
DB::commit();
return $this->success('Signup Successfully Done, please check your email to activate account', $newUser);
} catch(\Exception $e) {
DB::rollback();
Log::error($e);
return $this->error($e->getMessage(), $e->getCode());
}
}
}
Controller
use App\Interfaces\Auth\AuthInterface;
class AuthController extends Controller
{
protected $authInterface;
public function __construct(AuthInterface $auth)
{
$this->authInterface = $auth;
}
public function register(Request $request)
{
return $this->authInterface->register($request);
}
}
When I did php artisan route:list, I got this error:
Illuminate\Contracts\Container\BindingResolutionException
Target [App\Interfaces\Auth\AuthInterface] is not instantiable while building [App\Http\Controllers\Api\V1\Auth\AuthController].

2 C:\xampp\htdocs\myapp\vendor\laravel\framework\src\Illuminate\Container\Container.php:714
Illuminate\Container\Container::build("App\Interfaces\Auth\AuthInterface")
How do I get it resolved?
Thanks

It might be from your namespace, I had the same issue...it came from my namespace
