Deploying Node and Angular to Heroku error

I'm trying to learn how to deploy a Node and Angular app to Heroku and am getting an error.

Here are the steps I'm taking

  1. Create an empty repo on GitHub.

  2. Deploy the pre-create project, which creates a new heroku app.

Next, I download and copy the code that is in the pre-created project.

Then I push that code up to the empty repo I created step 1.

I then go back to Heroku and manually deploy connecting my repo to it.

When deploying I get an error that I don't know how to resolve. This is strange to me since I have the pre-configured Heroku app along with the exact same code.

I ran into this problem while deploying to Heroku today. In your package.json, make sure you are correctly specifying node as your engine. Example:

"engines": {
  "node": "^8.0.0"
},
