I get this error when I want to log in my session but I don't know how to fix it, I need it very much because my graduation ceremony is tomorrow. First error in the line: $response = $kernel->handle( $request = Request::capture() )->send();

use Illuminate\Contracts\Http\Kernel;
use Illuminate\Http\Request;

define('LARAVEL_START', microtime(true));


if (file_exists($maintenance = __DIR__.'/../storage/framework/maintenance.php')) {
   require $maintenance;
}

require __DIR__.'/../vendor/autoload.php';


$app = require_once __DIR__.'/../bootstrap/app.php';

$kernel = $app->make(Kernel::class);

$response = $kernel->handle(
   $request = Request::capture()
)->send();

$kernel->terminate($request, $response);

Second error on last line

<?php



$publicPath = getcwd();
$uri = urldecode(

    parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH) ?? ''

);
if ($uri !== '/' && file_exists($publicPath.$uri)) {

    return false;

}
require_once $publicPath.'/index.php';

This is authClass

<?php

namespace App\Http\Controllers\Admin;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;

class AuthController extends Controller
{
    public function getLogin()
    {
        return view('admin.auth.login');
    }
    public function postLogin(Request $request)
    {
        $request->validate([
            'email' => 'required|email',
            'password' => 'required'
        ]);
        $validated = auth()->attempt([
            'email' => $request->email,
            'password' => $request->password,
            'is_admin' => 1
        ], $request->password);
        if ($validated) {
            return redirect()->route('dashboard')->with('success', 'Login Successfull');
        } else {
            return redirect()->back()->with('error', $request);
        }
    }
}

This line is written as follows: return redirect()->back()->with('error', 'Invalid Credentials'); I changed it to only know the error

In Laravel, serialization of closures is not allowed by default. This restriction exists because closures are anonymous functions and can contain references to surrounding context and variables. Serializing closures and their surrounding state can be complex and error-prone.

When you try to serialize closures in Laravel, you may encounter errors similar to the following:

To work around this limitation, you can refactor your code to avoid serializing closures. Instead, you can use other serializable types, such as classes or data structures (such as arrays or objects).

If you need to store some state or behavior, you can create a class and define the required methods or properties. You can then serialize and deserialize instances of that class without any problems.

The following is an example of using closures to refactor code into classes:

class MySerializableClass
{
    public function doSomething()
    {
        // Your code here
    }
}

$serializableInstance = new MySerializableClass();

// Serialize the instance
$serialized = serialize($serializableInstance);

// Unserialize the instance
$unserialized = unserialize($serialized);

// Call the method on the unserialized instance
$unserialized->doSomething();

By using serializable classes, you can safely serialize and deserialize instances without running into any issues related to closures.

Remember that closures are a powerful feature in PHP, but they have limitations when it comes to serialization. Refactoring your code to use serializable classes can help you overcome this limitation in Laravel.
