Heroku build suddenly failing

Wappler General

I have spent hours trying to resolve.

Heroku logs only hint is:

Installing dependencies
Installing node modules (package.json + package-lock)
npm ERR! cb.apply is not a function

yet, there is no cb.apply in either file.

Has anyone else had - and recovered from an error such as this?

Hi Elle,

Maybe this is a Heroku problem? try contacting their support see if they can find more info about the problem.

I am currently experiencing the exact same thing trying to push my node.js app to Heroku. I have seemingly changed nothing personally that would have caused this.

I’ll reply here if I happen to find a resolution. I would very much appreciate if anyone else could do the same

What my heroku log looked like was this:

What resolved it for me was to go to my package.json and package-lock.json and change the versions under engines. I also updated my local node.js version to the current version.

In my package.json and package-lock.json, engines was:

"engines": {
    "node": ">=14.15.0"
  }

and I updated them both to have:

"engines": {
    "node": ">=20.x",
    "npm": ">=10.x"
  }

Could you get hold of this log file to see the errors there?

Seems they made the node versions specification on Heroku pretty strict… while the version we specify is pretty valid.

Maybe you should pass that as a bug to their support as well.

Followed all suggestions here to no avail.

What did work was running this in CLI:

heroku config:set BUNDLE_WITHOUT=“development:test” -a appName
