Heroku "Process exited with status 137" node.js app
heroku, javascript, mongodb, node.js
Solution
I checked the logs, it said that `at=error code=H10 desc="App crashed"`, it means you have `uncaught Exception`, so you should check your code.
if you want to use `mongodb` on Heroku, you should try to add the `mongodb addon` for your application. you can find the doc here
and try to use `process.env.PORT`, not the port you want to use.
if it doesn't still solve your problem, you can try to use this command `heroku run bash`, this command can make you into heroku environment and start your server.
Problem
I recently posted a question on a similar topic. I did a major overhaul of everything on the URL, and the same thing happened as last time: I could deploy everything and run it using `heroku local web`. When I went to the web dyno, it said I had an application error and I then check the logs. Here is what it said (I am using a project on github called atwork): ``` 2017-05-02T02:35:39.191493+00:00 app[web.1]: Loaded model: chats.js 2017-05-02T02:35:39.200517+00:00 app[web.1]: Loaded model: streams.js 2017-05-02T02:35:39.196830+00:00 app[web.1]: Loaded model: posts.js 2017-05-02T02:35:39.209761+00:00 app[web.1]: Loaded model: users.js 2017-05-02T02:35:40.067321+00:00 app[web.1]: AtWork running at http://:::8111 2017-05-02T02:35:50.116492+00:00 heroku[router]: at=error code=H20 desc="App boot timeout" method=GET path="/" host=room111-thoughts.herokuapp.com request_id=44a6e779-e6b8-4a33-a5b9-53430af2ad8f fwd="108.221.62.78" dyno= connect= service= status=503 bytes= protocol=https 2017-05-02T02:36:35.859814+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch 2017-05-02T02:36:35.859903+00:00 heroku[web.1]: Stopping process with SIGKILL 2017-05-02T02:36:35.956564+00:00 heroku[web.1]: Process exited with status 137 2017-05-02T02:36:35.969766+00:00 heroku[web.1]: State changed from starting to crashed 2017-05-02T02:37:22.933285+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=room111-thoughts.herokuapp.com request_id=80ffc71f-d792-4538-b50a-5140b7658819 fwd="108.221.62.78" dyno= connect= service= status=503 bytes= protocol=https ``` I am a beginner to Heroku and Node.js, so any help is appreciated. I will provide any information needed to find an answer.
