This is a follow on question to my Heroku / Clojure problem here. As outlined in that thread, I was able to push my app to Heroku’s master, and that deploys it.

But when I try to go to my app’s URL, I get the below error. It’s a bizarre port error, but I didn’t think I had control over those details when deploying a Clojure app on Heroku. I think my setup’s pretty straightforward. Is there anything I can do to address this error?

Procfile


    web: lein run -m http.handler

http.handler


    ...
    (def app      (handler/site main))

Error

There seems to be a similar problem with Nodejs. But again, I don’t think I have control of port assignments in a Compojure / Ring / Jetty deployment. Am I wrong? Would the behaviour change with Webnoir?

Thanks

    Although I got some really good hints, I wasn able to finally get past this. It turns out my project.clj had a defproject that included this JDPA config: 

    
    :jvm-opts ["-agentlib:jdwp=transport=dt_socket,server=y,suspend=n"]

    I should have noticed it earlier. But it just works locally, so I didn’t think to question it. Hope this helps others who are having the same roadblock.
