    I don’t know how to help you directly, but when I get a strange error message I try to search for it, e.g. search for “Error [ERR_REQUIRE_ESM]: require() of ES Module”.

    Or read the sentence that says “Instead change the require of index.js…” and do like it says. If you don’t know what a “dynamic import()” is (I also don’t know what it is), google for that.

    My first impression is that it says you’re trying to load an ES Module using a CommonJS require() call. Evidently from your code snippet, that’s not the case. My guess would be that Typescript is transpiling your code to CommonJS modules, and that the library you’re trying to import only exports ES modules (or at-least that’s what NodeJS is trying to import for one reason or another).

    You may have to modify something in your tsconfig.json file to tell it to transpile to ESM instead of CommonJS.
