Hi i am trying to deploy my project i develop in Clojure to heroku. it created and build too but
when i write heroku open it gives error and logs saying missing build
You are using heroky "autodetect" and it's detecting your npm file and trying to start it as a npm project.
You need to specify to use clojure buildpack in somewhere inside heroku settings.
I recommend you to move into "docker mode" in heroku, that will give you more control about how to build/run your project.
