/auth Error from IdP: access_denied - Cannot set property 'execution' of undefined

I have setup a new vouch-proxy server with a simple website that has protected content. I am using certcache to provide wildcard ssl - https://watchremote.uk
I want the user to authenticate via auth0 and be passed through to the protected content at https://watchremote.uk/protected
Try it and you will see my problem is the title of this post
Can someone please give me a clue as to what to try?
Thanks
