Laravel7 - Redirect on specific view when throttling detected

Question

I need to redirect the user to a simple informative view when throttling is detected during login.

I have a view called suspended.blade.php

I have set a route

Route::get('/suspended', function(){
    return view('suspended');
});

I'm using Cartalyst/Sentinel.

In my login controller I have something like this:

function LoginUser(Request $request){
   // some validation stuff...
  
   try {
     $user = Sentinel::authenticate($request->all());
   } catch (ThrottlingException $e) {
     // user inserted too many times a wrong password
     return redirect('/suspended');
   } catch (NotActivatedgException $e) {
     return redirect()->back()->with( ['error' => "Account not active yet."] );
   }

   // some other stuff...
}

If I emulate trottling I only get an error page, instead of my view.

Why is that?

Thanks

EDIT Following the hints of @PsyLogic I modified my function like that:

function LoginUser(Request $request){
   // some validation stuff...
  
   try {
     $user = Sentinel::authenticate($request->all());
   } 
   /* remove this part to use the default behaviour described in app\Excpetions\Handler.php */
      // catch (ThrottlingException $e) {
      // return redirect('/suspended');
      // } 
   catch (NotActivatedgException $e) {
     return redirect()->back()->with( ['error' => "Account not active yet."] 
   );
 }

   // some other stuff...
}

Still does not work, and shows the Laravel Error Page with all the debug code.

Answer 1

Laravel already has throttle middleware you can just extend it and update the handle() method

namespace App\Http\Middleware;

use Illuminate\Routing\Middleware\ThrottleRequests;

class CustomThrottleMiddleware extends ThrottleRequests
{
     //...
}

and update the new middleware in your Handle.php file

protected $routeMiddleware = [
        'auth' => \App\Http\Middleware\Authenticate::class,
         // ...
        'throttle' =>App\Http\Middleware\CustomThrottleMiddleware::class,
]

or you may keep the original index throttle and add your s

protected $routeMiddleware = [
            'auth' => \App\Http\Middleware\Authenticate::class,
             // ...
            'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
            'custom_throttle' =>App\Http\Middleware\CustomThrottleMiddleware::class,

    ]

Updated (easy way)

Event those changes won't affect your package, but let's do it with easy way, you can update the render() function inside App\Exceptions\Handler::class and make a test

public function render($request, Throwable $exception)
    {
        if ($exception instanceof ThrottleRequestsException) {
            return redirect()->route('suspended'); 
        }

        return parent::render($request, $exception);
    }
