thank you for the great resource you've created!!!
I'd appreciate help resolving this error:

in svg-world-map.js

// Wait for asynchronous svg load
svg.addEventListener("load", async () => {
let promise2 = new Promise(resolve2 => {
// Set SVG base node
baseNode = svg.getSVGDocument().children[0];
// Startup SVG path traversing, then country sorting, followed by click handlers, etc.
initMapCountries();
