Deploy Node-RED to Heroku - node.js

Question

I found out the files included in the Github repo that used to connect to the Heroku server and substituted with my own package.json, flow .json, repo link in app.json. After deploying, I tried opening app and received an error from the logs window of Heroku CLI as below:
2021-04-13T10:22:01.693823+00:00 heroku[web.1]: Starting process with command `node --max-old-space-size=384 node_modules/node-red/red.js --settings ./settings.js --userDir ./`

Hope to get your help. Thanks.

You have removed Node-RED from the package.json, so since it's not installed it won't start.
{
"name": "node-red-project",
"description": "A Node-RED Project",
"version": "0.0.1",
"dependencies": {
"node-red-contrib-alarm": "~1.2.5",
"node-red-contrib-component-dashboard": "0.0.4",
"node-red-contrib-components": "~0.1.8",
"node-red-contrib-firebase": "~1.1.1",
"node-red-contrib-influxdb": "~0.5.1",
"node-red-contrib-mqtt-broker": "~0.2.4",
"node-red-contrib-remote": "~1.1.3",
"node-red-contrib-ttn": "~2.0.5",
"node-red-contrib-ui-svg": "~2.2.1",
"node-red-contrib-users": "~0.1.9",
"node-red-dashboard": "~2.14.0",
"node-red-node-ui-table": "~0.3.10"
}
}
If you want to add extra nodes, you need to add these to the list of dependencies in the existing package.json not just replace them.
{
"name": "nodered-heroku",
"version": "0.0.7",
"dependencies": {
"when": "3.7.8",
"nano": "8.2.2",
"feedparser":"2.2.10",
"node-red-dashboard":"2.23.3",
"redis":"3.0.2",
"node-red": "1.1.3",
"node-red-node-tail": "0.1.1",
"node-red-contrib-aedes": "0.3.6",
"node-red-contrib-blynk-ws": "1.0.3",
"node-red-node-email": "1.7.9",
"node-red-node-ui-list": "0.3.1",
"node-red-contrib-telegrambot": "8.4.0",
"node-red-contrib-alarm": "~1.2.5",
"node-red-contrib-component-dashboard": "0.0.4",
"node-red-contrib-components": "~0.1.8",
"node-red-contrib-firebase": "~1.1.1",
"node-red-contrib-influxdb": "~0.5.1",
"node-red-contrib-mqtt-broker": "~0.2.4",
"node-red-contrib-remote": "~1.1.3",
"node-red-contrib-ttn": "~2.0.5",
"node-red-contrib-ui-svg": "~2.2.1",
"node-red-contrib-users": "~0.1.9",
"node-red-node-ui-table": "~0.3.10"
}
}
I would also suggest you use the latest version of Node-RED (1.3.1 at time of posting) as 1.1.3 is VERY OLD
