Laravel Cors Access-Control-Allow-Origin

Question

Suddenly getting the following alarm

Cross-Origin Read Blocking (CORB) blocked cross-origin response http://traxit-backend.test/api/register with MIME type text/html. See https://www.chromestatus.com/feature/5629709824032768 for more details.

Failed to load http://traxit-backend.test/api/register : Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ' http://localhost:8080 ' is therefore not allowed access.

OPTIONS http://traxit-backend.test/api/register 500 (Internal Server Error)

It's been working fine with my configuration but just started acting up today. Im not sure if i need to do something. Tried different things I've read about on the internet with no luck

kernal.php file

protected $middleware = [
        \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
        \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
        \App\Http\Middleware\TrimStrings::class,
        \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
        \App\Http\Middleware\TrustProxies::class,
        \Barryvdh\Cors\HandleCors::class,
    ];

cors.php file

  'supportsCredentials' => false,
    'allowedOrigins' => ['*'],
    'allowedOriginsPatterns' => [],
    'allowedHeaders' => ['*'],
    'allowedMethods' => ['*'],
    'exposedHeaders' => [],
    'maxAge' => 0,

];

im using vuejs with axios on my front end. using laravel passport for access tokens.

Answer 1

added 'allowedHeaders' => ['Access-Control-Allow-Origin', '*'],

Not sure what changed, but it fixed it

'supportsCredentials' => false,
    'allowedOrigins' => ['*'],
    'allowedOriginsPatterns' => [],
    'allowedHeaders' => ['Access-Control-Allow-Origin', '*'],
    'allowedMethods' => ['*'],
    'exposedHeaders' => [],
    'maxAge' => 0,

];
