mcrypt_module_open() is deprecated error on laravel 5.4 + consolibyte quickbooks

Good Day,

I tried integrating Quickbooks into laravel 5.4, I saw this tutorial in the net "http://ift.tt/2h2UVsp" I have successfully installed it on my localhost, also added the plugin successfull.

Now When I tried to use the connect button which accesses to oauth url.. I get to be redirected to QB page where it asks you to authorize the app or not.. when I clicked authorized button.. I got error from my laravel app
