[Bug] route:list error when enabling email verification

[mrinaldidfs]

Bug report

Once email verification routes are enabled, the route:list command gives the following error message:

 Undefined array key "signed"
  at vendor\backpack\crud\src\app\Http\Controllers\Auth\VerifyEmailController.php:23

What I did

I set the setup_auth_routes and setup_email_verification_routes values ​​to true

What I've already tried to fix it

In this case I was unable to resolve the issue even though the signed middleware was declared correctly.

Is it a bug in the latest version of Backpack?

After I run composer update backpack/crud the bug... is it still there?
yes

The error you’re encountering—Undefined array key "signed" in VerifyEmailController.php when running php artisan route:list after enabling email verification routes—suggests that the signed middleware alias is not properly registered in your Laravel application.

According to the Backpack documentation for enabling email verification, you must ensure that the signed middleware is correctly defined in your HTTP kernel. For Laravel 10 and above, you should have something like this in your app/Http/Kernel.php:

protected $middlewareAliases = [
    // ... other middleware aliases
    'verified' => \Illuminate\Auth\Middleware\EnsureEmailIsVerified::class,
    'signed' => \App\Http\Middleware\ValidateSignature::class, // or the default Laravel one
];

If the signed middleware is missing from this array, Backpack will throw the "Undefined array key 'signed'" error when it tries to use it in the email verification routes. Double-check that this alias exists and is spelled correctly.

If you’re using a custom ValidateSignature middleware, make sure it’s implemented and referenced properly. The Backpack docs also mention you can copy the default middleware from the Laravel repository if needed.

Summary of steps to fix:

1. Open app/Http/Kernel.php.
2. Ensure the signed middleware alias is present in the $middlewareAliases array.
3. If missing, add:

   'signed' => \Illuminate\Routing\Middleware\ValidateSignature::class,

   or your custom implementation if you have one.

This should resolve the error you’re seeing with route:list after enabling email verification routes in Backpack. For more details, see the official documentation: Enable email verification in Backpack routes (Step 3)https://backpackforlaravel.com/docs/6.x/base-how-to.

If you have already done this and the error persists, double-check for typos or issues in your Kernel.php, and ensure you have cleared your config cache with php artisan config:clear.

In Laravel 12 there is no app/Http/Kernel.php file as the basic middleware is already automatically defined.
