Heroku Hapi 503 Bug

Press this to deploy this "app" to Heroku. It takes 1 min to have the app running

Minimal Hapi code base to reproduce random 503 status code bugs in Heroku.

To test the behavior, run the following command enough times. At some point Heroku should respond with 503 Application Error even though the request is the same all the time.

curl -d'a' https://heroku-hapi-503-bug.herokuapp.com

With the exact same commands, sometimes you get normal response, sometimes 503 Application Error, with reason "Server Request Interrupted".

Deploy

• Create a Heroku app
