How to stop the little hero in the process

Question

I accidentally added npm startheroku to the message build process, so now the build progress is stuck.

I did git push heroku master, the assembly started fine, and my server started the same way as when it started npm start, but since it npm startwas in the post-assembly, it never finished. Since I am on a free account, I have only one parallel build process, and due to being stuck, I cannot create a new version.

I already tried heroku ps -a APP_NAMEand then heroku ps:kill web.1for one running process, but that didn't help.
