Fortify can't return Inertia Response

[amiranagram]

• Fortify Version: 1.4.0
• Laravel Version: 8.4.0
• PHP Version: 7.4.3
• Database Driver & Version:

Description:

TypeError
Argument 1 passed to Symfony\Component\HttpFoundation\Response::setContent() must be of the type string or null, object given, called in laravel\framework\src\Illuminate\Http\Response.php on line 65

I did some debugging, and basically when you return an Inertia response in a common controller Illuminate\Routing\Router::toResponse() receives Inertia\Response object where then it calls its own toResponse() to return Illuminate\Http\Response and all is good.

But, using:

Fortify::loginView(function () {
    return inertia('Auth/Login');
});

it fails to build the response because of the SimpleViewResponse and simply returns and Inertia\Response object instead of a string, hence the error above.

Steps To Reproduce:

Configure Inertia, make a Vue component resources/js/Pages/Auth/Login.vue and in FortifyServiceProvider::boot() paste:

Fortify::loginView(function () {
    return inertia('Auth/Login');
});

I came to leave this exact issue. Thanks @classjunky

UPDATE:

Here's a quick fix:

Fortify::loginView(function (Request $request) {
    return inertia('Auth/Login')->toResponse($request);
});

I have the same problem, any official solution?

[amiranagram]

@leo95batista The solution I provided above works just fine, you can see that on https://xp.amirrami.com.

Although I wish for a simpler solution, since I, like most Laravel developers like to keep it simple.

Feel free to pr, thanks.

Could you tell me how to exactly config Inertia in FortifyServiceProvider? This is how i have FortifyServiceProvider

This solution is causing
ErrorException strpos() expects parameter 1 to be string, object given

from \vendor\laravel\framework\src\Illuminate\View\ViewName.php:17

for me

Edit: Updating composer dependencies AND using double quotes on "Auth/Login" has fixed it

I wonder if this is what you're looking for... maybe this could help you or someone out there :)

Using Inertia alone...

Fortify::loginView(function () {
    return Inertia::render('Auth/Login');
});

OR

Using Ziggy with Inertia...

  Fortify::loginView(function () {
      return route('login');
  });

Given that route('login') is declared as...

//routes/web.php

Route::get('login', [LoginController::class, 'create'])->name('login');

//Auth/LoginController.php

public function create(Request $request, Router $router)
{
    return Inertia::render('Auth/Login');
}
