Heroku-postbuild error when deploying nodejs and angular to heroku - node.js

Question

I have a app that is currently deployed on heroku and working perfectly fine. I created a new heroku app and tried to run the same branch. I installed nodejs and all the configuration is the same but for some reason the build is failing at heroku-postbuild: "ng build --prod". It works fine on the previous instance I have on heroku but wont work on the new one. I don't know what i am missing as the information on the error is minimal. I am attaching my package.json as well as the error message I get. any help will be appreciated and let me know if you need me to upload anything else.

'node-sass' usage is deprecated and will be removed in a future major version. To opt-out of the deprecated behaviour and start using 'sass' uninstall 'node-sass'.

Answer 1

Check if HEROKU_API_KEY is correct and that heroku_app_name is unique. Also this line seems sketcy: Detected both "build" and "heroku-postbuild" scripts Running heroku-postbuild. Maybe refactor heroku-postbuild in build and run only build.
"scripts": {
"ng": "ng",
"main": "server.js",
"preinstall": "npm install -g #angular/cli #angular/compiler-cli typescript",
"start": "ng serve",
"build": "ng build --prod",
"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e"
},

Answer 2

I managed to solve the issue by changing the version of #angular/compiler-cli and #angular/compiler versions.
