Facebook auth broken

[Chartman123]

When I try to authenticate via Facebook I get the following error:

Fatal error: Uncaught TypeError: implode(): Argument #2 ($array) must be of type ?array, string given in /config/www/gallery/plugins/oAuth/include/hybridauth/Hybrid/thirdparty/Facebook/base_facebook.php:1309
