Getting "Incomplete response received from application" in Rails

Question

Can someone please help? My stack is ubuntu-server 14.04 with nginx/passenger and ruby 2.2.2. I can't manage to make my project work in production. Everything runs ok in development.

secrets.yml

production:
  secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>
  secret_token: <%= ENV["SECRET_KEY_BASE"] %>

server

server { 
    listen 80; 
    server_name logvs.local; 
    passenger_enabled on; 
    passenger_app_env development;
    root /var/www/logvs/public; 
}

error.log

Have you defined the missing environment variables? Until you do it will not run. – Gonagle

Thanks to this line of code I could solve the problem in our server passenger_app_env development; – Homage

Thank you, passenger_app_env solve my issue too. – Contort

Answer 1

I had the similar problem. I ended up with manually entering env variables in the production in the .profile (or something similar) file in the production server.

I've found good answer there How to solve error "Missing `secret_key_base` for 'production' environment" (Rails 4.1)

Answer 2

I got really stuck with this problem because I had the problem before on my production server and I fixed it by setting my secret_key_base. However, now the problem started happening in my development environment. I'm using NGINX in my development environment but I still have MAMP installed separately and so the rails app was using the MySQL installed by MAMP, which appeared to be running. Somehow it had a bug, however, and I restarted MySQL and then it fixed the problem. So that's something to try: make sure MySQL (or whatever database you're using) is configured correctly, running, and if it is, try restarting it.
