Today when I try to sign in via Facebook to my Laravel project, I got an error
Undefined variable: access_token vendor/laravel/socialite/src/Two/FacebookProvider.php
If you use fersion ~1.0
To make it work normally with hotfix, open vendor/laravel/socialite/src/Two/FacebookProvider.php and replace
parse_str($body, $data);
return $access_token;
with
parse_str($body, $data);
$json = json_decode(key($data));
return $json->access_token;
For version 3
parse_str($response->getBody(), $data);
$json = json_decode(key($data), true);
return Arr::add($json, 'expires_in', Arr::pull($json, 'expires'));
