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.**
