Just updated a Rails 4.2 app to 5.2.1 and having trouble pushing it to Heroku. Errors below. I've tried what's recommended here and here by adding following to my rack_timeout.rb initializer.

Rails.application.config.middleware.insert_before Rack::Runtime, Rack::Timeout, service_timeout: 5

But that doesn't help. Thoughts?

$ git push heroku

In config/initializers/rack_timeout.rb at line 2, you're doing Rack::Timeout.timeout =

This method doesn't exist anymore in the most recent versions of rack timeout. Since you upgraded, you need to change your code as well.

The rack-timeout readme indicates how you can configure rack-timeout with your rails app: https://github.com/heroku/rack-timeout#rails-apps-manually
