Deploying ruby ​​google cloud api

Question

I am new to google cloud and I have this problem when I try to deploy my ruby ​​api in google cloud, here is what I did:

I uploaded my ruby ​​api to github (it works fine on localhost), here -> https://github.com/guisantogui/it

I got acquainted with the Google global textbook → https://cloud.google.com/ruby/getting-started/hello-world

and it worked as expected, but when I download my application, I received this message http 502 bad gateway, here are the logs:

2017-10-30 23:48:53 default[20171030t213633]  => Booting Puma

2017-11-01 10:55:02 default[20171030t213633]  "GET /tatoo_artis/list" 502

And finally, and I think the more important app.yaml file is:

entrypoint: bundle exec rails server Puma -p 3000
env: flex
runtime: ruby

Thanks in advance, I did not understand what the problem is and how to fix it!
