Twitter login with my own shim server not working



I’ve set up node-auth-shim at Heroku.In the client (hello.js) I changed oauth_proxy to point to my proxy url

When I hit the Twitter button, everything looks working fine but when it comes from twitter, it opens my callback url with below querystringparamater :

proxy_url=http://{my app}{

As you see it’s retruning state blank, can’t get any information and authentication.

It works fine if i use direct proxy which is by default as i am using hello.js

Please advise or let me know if you have more question
