I believe this is a known issue with the latest versions of Node. See for example this thread.
The sample application works with Node.js 14. You can see what version of Node.js you are using with node --version. Presumably you are using a version of Node.js that is more recent than version 14. What to do?
Supporting multiple versions of Node on a single machine has historically been challenging. There are lots of solutions out there.
- If you have no other reason to have Node.js on your machine, you could uninstall your current version and install Node.js v. 14.
- If you want to be able to use multiple versions of Node.js on your machine, nvm is a popular solution.
Let us know how it goes.
