ITP RouteNotFoundException

[mikeastral]

According to the Upgrading instructions, when upgrading from version 15.x.x to version 16.0.0 it is suggested to append the itp middleware into any custom routes defined. However, when adding the itp middleware a RouteNotFoundException will be thrown.

Symfony\Component\Routing\Exception\RouteNotFoundException
Route [] not defined.

Thrown by vendor\laravel\framework\src\Illuminate\Routing\UrlGenerator.php:429

Is there any other configuration required before appending the ITP middleware?

The changes made were as follows:

ORIGINAL (working fine):

Route::middleware(['auth.shopify', 'billable'])->group(function () {

    Route::get('/faq', [HolidayController::class, 'faq'])->name('faq');
});

CHANGES (throwing Exception):

Route::middleware(['itp', 'auth.shopify', 'billable'])->group(function () {

    Route::get('/faq', [HolidayController::class, 'faq'])->name('faq');
});

Found out that I needed to add the new routes into my shopify-app.app file in order to fix the issue

'itp' => env('SHOPIFY_ROUTE_NAME_ITP', 'itp'),
'itp.ask' => env('SHOPIFY_ROUTE_NAME_ITP_ASK', 'itp.ask'),
