Fortify - Target [Illuminate\Contracts\Auth\StatefulGuard] is not instantiable

I've installed Fortify locally and implemented the login routes as well as 2FA without any issues (i.e. users can login, enable it, scan the QR code, input a code to confirm and after that it will always ask for a 2FA code when logging in). However, after deploying it on Heroku, I was getting a 404 when hitting /login. If I run php artisan route:list I could still see all of Fortify's routes. Weird. So I decided to move them to routes\web.php and add Fortify::ignoreRoutes(); to the register method in FortifyServiceProvider.php. It worked. But after trying to log in I got this error:

Target [Illuminate\Contracts\Auth\StatefulGuard] is not instantiable while building [Laravel\Fortify\Http\Controllers\AuthenticatedSessionController].

I then also added this to the register method in FortifyServiceProvider.php :

$this->app->bind(StatefulGuard::class, function () {
    return Auth::guard(config('fortify.guard', null));
});

This fixed the previous problem, the user was logged in, but I still got this error:

Target [Laravel\Fortify\Contracts\LoginResponse] is not instantiable.

And when I tried to enable 2FA I got this error:

Target [Laravel\Fortify\Contracts\TwoFactorAuthenticationProvider] is not instantiable.

This is as far as I got. I'm sure there must be a "hack" to prevent this error but this can't be the proper way to fix it. I followed the official instructions and got it to work locally so obviously the different environment is the key factor. I just can't think of anything that could cause this. Some extra configuration in Heroku I'm missing, perhaps?

Thank you to anyone who can help me with this!

It sounds like you may need to register the Fortify service provider in your config/app.php file. This should be done after all of your other service providers are registered.

'providers' => [
    // Other Service Providers

    Laravel\Fortify\FortifyServiceProvider::class,
],

You may also need to make sure that the config/fortify.php file is configured correctly. Make sure that the guard option is set to the guard that you are using for authentication.

'guard' => 'web',

If you are still having issues, you may need to clear your application cache with the php artisan config:cache command.

I hope this helps!

@LaryAI Thanks Lary, I had done all 3 things already but unfortunately it didn't help. Though I believe if I hadn't, it wouldn't be working locally either.

@Silas_MK Unfortunately, I never got to fix this issue BUT I recently came across a similar issue which took me countless hours to find a solution. In the end, this is what worked for me - just adding that just adding that extra configuration. Given the similarities in the error messages, I have a feeling this could be the root problem. Let me know if it works!

@antoniolima I ran into this same issue and here is what I added to my custom fortify service provider to get both issues resolved:

class FortifyServiceProvider extends ServiceProvider
{
    public function register(): void
    {
        // Bind the guard Fortify controllers expect
        $this->app->bind(StatefulGuard::class, function () {
            $guard = config('fortify.guard', 'web');

            return Auth::guard($guard);
        });

        // Bind the two-factor redirector contract to Fortify's default action
        $this->app->bind(
            RedirectsIfTwoFactorAuthenticatable::class,
            RedirectIfTwoFactorAuthenticatable::class
        );
    }

    public function boot(): void
    {
        // ... existing code ...
    }
}

This has worked for me so far, but I am still testing. If you'd like to see the entire Fortify and Jetstream service providers, let me know.

I hope this helps.
