Laravel with Linkedin API error - ServiceFactory::createService() must be an instance of OAuth\Common\Storage\TokenStorageInterface

Question

I'm using Laravel to develop my website, and I integrated the linkedin login to it, it works fine for like a few months. then suddenly, last week i received an error. I didn't change any code that has something to do with Linkedin API. I'm suspecting whether it has something to do with Linkedin itself.

here's what the error looks like:

If you are using this library to integrate Linkedin to your laravel project, there might be an issue right now with the update. you can simply fix the error in OAuth.php by replacing it with this code:
