How to Fix "Route [login] not defined" Error During Impersonation in Filament

Hello, I am building an "Impersonate" feature for a super admin in my Filament v3 application and I'm facing a routing issue. I have already implemented most of the feature, but I'm stuck on a specific error.

My Goal I want to add an "Impersonate" button to my CompanyResource table. When a super admin clicks this button:

A confirmation modal should appear.

After confirmation, the super admin should be logged in as the first user of that company.

The UI should refresh, and a banner should appear at the top saying "Impersonating [User Name] – [Stop Impersonation]".

Clicking "Stop Impersonation" should log the super admin back into their own account and remove the banner.

My Current Implementation I have already set up the following code based on a guide:

Impersonate Action in CompanyResource.php:

// In app/Filament/Resources/CompanyResource.php -> table() method Action::make('impersonate') ->label('Impersonate') ->icon('heroicon-o-user-circle') ->visible(fn (): bool => auth()->user()->is_super_admin) ->requiresConfirmation() ->modalHeading('Impersonate User') ->modalDescription(function (Company $record) { $userToImpersonate = $record->users()->first(); $userName = $userToImpersonate ? $userToImpersonate->name : 'a user'; return "You are about to impersonate {$userName} from {$record->name}. Continue?"; }) ->action(function (Company $record) { $userToImpersonate = $record->users()->first(); if (!$userToImpersonate) { // Error notification logic... return; } session(['impersonator_id' => auth()->id()]); Auth::login($userToImpersonate); return redirect(static::getUrl()); }); Route for Stopping Impersonation in routes/web.php: use App\Http\Controllers\ImpersonationController; Route::get('/impersonate/stop', [ImpersonationController::class, 'stop'])->name('impersonate.stop'); 3. ImpersonationController to handle stopping: // In app/Http/Controllers/ImpersonationController.php class ImpersonationController extends Controller { public function stop() { $impersonatorId = session('impersonator_id'); if (!$impersonatorId) { return redirect('/admin'); } Auth::login(User::find($impersonatorId)); session()->forget('impersonator_id'); return redirect('/admin'); } } 4. Impersonation Banner using a renderHook in AdminPanelProvider.php: ->renderHook( 'panels::body.start', fn () => session()->has('impersonator_id') ? view('filament.components.impersonation-banner') : '' ) The view file impersonation-banner.blade.php contains the banner HTML and the link to the impersonate.stop route. The Problem I'm Facing Everything works up to a point. When I click the "Impersonate" button and confirm, the application crashes and shows the error: Route [login] not defined.

I believe this is happening because when I use Auth::login() to switch users, Laravel's authentication middleware gets triggered and tries to redirect to a default login page named login, which does not exist in my Filament setup. My Filament login route is named filament.admin.auth.login.

My Question How can I solve the "Route [login] not defined" error in this specific scenario?

I need a clear explanation and code example that shows how to correctly instruct Laravel to use Filament's login route (filament.admin.auth.login) when an authentication check fails within the admin panel, especially during this impersonation process. I suspect I need to modify the app/Http/Middleware/Authenticate.php file, but I need the correct implementation for a Filament-based application.

You're correct: the error occurs because Laravel's default Authenticate middleware tries to redirect unauthenticated users to a route named login, which doesn't exist in Filament. Filament uses its own route name for the login page (usually filament.admin.auth.login).

To fix this, you need to override the redirectTo() method in your app/Http/Middleware/Authenticate.php middleware to point to Filament's login route when the user is not authenticated in the admin panel.

Here's how to do it:

Step 1: Update app/Http/Middleware/Authenticate.php

Find your Authenticate middleware (usually at app/Http/Middleware/Authenticate.php) and override the redirectTo() method as follows:

protected function redirectTo($request)
{
    // If the request is for the Filament admin panel, redirect to Filament's login route
    if ($request->is('admin') || $request->is('admin/*')) {
        return route('filament.admin.auth.login');
    }

    // Otherwise, use the default login route (if you have one)
    return route('login');
}

Explanation:

The redirectTo() method is called when authentication fails.
The if ($request->is('admin') || $request->is('admin/*')) check ensures that any route under /admin (Filament's default prefix) will redirect to Filament's login route.
Adjust 'admin' if you use a custom admin path.

Step 2: (Optional) Remove the Default login Route

If you don't have a standard Laravel login page, you can safely remove or ignore the default login route.

Step 3: Clear Cache

After making changes, clear your route and config cache:

php artisan route:clear
php artisan config:clear

Summary

By customizing the redirectTo() method, you ensure that any authentication failure in the Filament admin panel redirects to the correct Filament login route, fixing the "Route [login] not defined" error during impersonation.
