You'll get this error when you're hosting a Laravel project with using HTTPS/SSL protocol on localhost or 127.0.0.1:

cURL error 60: SSL certificate problem: unable to get local issuer certificate (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)

I read some article on trying to install cacert.pem authorization certificate on your WAMP/XAMPP setup but it didn't really work out for me as I was running out of time.

So, I did a little digging and learnt that I can just modify the verify flag to false in the vendor/guzzlehttp/guzzle/src/Client.php file:

<?php
$defaults = [
    'allow_redirects' => RedirectMiddleware::$defaultSettings,
    'http_errors'     => true,
    'decode_content'  => true,
    'verify'          => false, // changed it to false
    'cookies'         => false
];
?>

By changing to it false, you'll not face that error again but please keep in mind, you should do this only if you're developing on localhost.

Happy coding!
