Ruby on Rails

thanks a lot for the advise. I migrated to Heroku and I have the following problem with facebook omniauth authentication. When I authenticate with facebook the callback URL does not work and I get sent to the homepage https://barteringapps.herokuapp.com/#_=_ with the following log error message :

In development the functionality works when I set callback-url in devise.rb and in the facebook App settings to http://127.0.0.1:5000/users/auth/facebook/callback

So to give a more detailed log (I omitted not important infos):

1. I click on the link for the sign in

   method=GET path="/users/sign_in" host=barteringapps.herokuapp.com fwd="81.171.81.200" status=200
   
   

2. I click for the sign in with facebook

   method=GET path="/users/auth/facebook" host=barteringapps.herokuapp.com fwd="81.171.81.200" status=302 INFO -- omniauth: (facebook) Request phase initiated. 
   
   

3. Callback from facebook, I notice that the path does not include my host

   method=GET path="/users/auth/facebook/callback?code='sometoken'" host=barteringapps.herokuapp.com fwd="81.171.81.200"
   
   

I already searched Stackoverflow for a solution and I followed this instructions Devise omniauth-facebook redirect_uri Url must absolute

1. I added :client_options

2. I configured the absolute path like so in devise.rb

   callback_url: ENV['SERVER_ROOT']+'/users/auth/facebook/callback'
   
   

3. In heroku settings I added the SERVER_ROOT env variable

I have also the following doubts, as I had many problems with env Varibles, I installed foreman gem for my development. Foreman works as my webserver and loads the ENV Variables from a env file. I have also a Procfile with the follwing code:

The problem is that production still runs with puma and without Procfile

Thanks a lot for your help Please give me a comment or just any tip to help me solve this
