How to fix /sanctum/csrf-cookie errors

Question

I am creating react js project with the Laravel Sanctum Axios API. When I get the sign-up page it shows the below error.

cors.php

<?php

return [

'paths' => ['api/*', 'sanctum/csrf-cookie','register', 'login' ],

'allowed_methods' => [ 
    'GET', 
    'POST', 
    'PUT', 
    'PATCH', 
    'DELETE', 
    'OPTIONS'],

'allowed_origins' => ['*'],

'allowed_origins_patterns' => [],

'allowed_headers' => [  
    'Origin',
    'Content-Type', 
    'Accept',
    'Authorization',
    'X-Requested-With',
    'X-CSRF-Token',
    
    ],

'exposed_headers' => [],

'max_age' => 0,

'supports_credentials' => true,

];

Now below error shown Access to XMLHttpRequest at 'http://localhost:8000/sanctum/csrf-cookie' from origin 'http://localhost:3000' has been blocked by CORS policy: Request header field x-xsrf-token is not allowed by Access-Control-Allow-Headers in preflight response.

You need to give access to your front localhost to send requests to the back-end API.

So I recommend you carefully follow the instructions from the laravel website: https://laravel.com/docs/8.x/sanctum#spa-configuration

and if you would have any questions about some steps you can ask me.

But I think your problem is that your front URL cannot send requests and you have to allow it. but anyway first you have to follow the steps from the link
