@nikspyratos Installed node and npm from Ubuntu repo's today. node -v returns 12.22.9

@swdrumm That's definitely not the latest. Long story short Ubuntu usually pegs some or other stable-but-not-modern version of things. Look at nvm and installing latest node.

For ref, my node -v returns 18.16.0

@nikspyratos OK, thanks. I'll upgrade node.js to a version that supports optional chaining.

@nikspyratos Works great with the latest version of node.js
I didn't realize the Ubuntu repo version was that old. Thanks for the help!
