Problems installing repository on Forge

Hi guys,

So i've just started to use Forge with Digital Ocean today and using repositories for the first time. It's almost been a breeze so far, but i'm having some problems installing a repository from an existing site. I'm not sure what or where to fix the bug so I can move on. It looks like it's not working great with the bindshared() method probably because it has been decrepitated. I've tested with a complete new Laravel installation from my developer machine -> GitHub -> Forge which works fine, but my existing site is having trouble.

Can anyone help? :)
