how do you solve it so it works on that nodejs?

You got 2 options:

1. install Node.js 14.x - this is the recommended solution; it will work for sure, but Node.js 14.x is no longer supported
2. use Node.js 16.x or a more recent version, and see if it works

Unfortunately, the Ember version used there is pretty old and I'm not sure if it works with Node.js 16+.
