Question

enter image description here

I have attached all the environment variables at heroku and pulled the code from github. After that i have tried to deploy the app. It run's well but build fails. (Github project link -> https://github.com/shubhamGhosh-dev/OAuth-messaging-server )

Answer 1

After two days of struggle, I found the issue. Which is just a script ( "build": "node index.js" ) in package.json file.

After removing "build": "node index.js" , the app is deployed successfully. But still curious for this behaviour.
