   Love,

!     Push rejected, failed to compile Node.js app.

From what I understand heroku try to runs my code with incorrect version of node.js, but why?

The repository hasn't been updated in 4 or more years and still depend on node.js 4 and lists the same on the package.json. It is a compatibility issue, before deploying change it to 6.0.0 and try, you might have luck.

Thank You a lot. That was the problem. Funny thing is that it worked several days ago on heroku, just fine. They must have update environments since then

Ran into the same issue recently which was a real pain, found a solution here https://devcenter.heroku.com/articles/nodejs-support

Currently, supported versions are 10.x, 12.x, 13.x, and 14.x.

You should always specify a Node.js version that matches the runtime you’re developing and testing with.

Updated node globally and specified the engine in package.json like:

"engines": {
"node": "10.20.x"

},

Hope this helps someone
