Problem with node v18

[slashinfty]

With the introduction of native fetch, I think some things have changed. I used to have a working app (months ago), but now it won't work. I mostly followed the node_direct example, though I had to change

const wasmPath = require("path").join(__dirname, "node_modules/stockfish/src/stockfish.wasm");

to

const wasmPath = require('url').pathToFileURL(require("path").join(__dirname, "node_modules/stockfish/src/stockfish.wasm"));

since this line was requiring a URL (this is where native fetch in node has altered things I believe, as this condition should only be true in a browser?).

However, I get the following error:

TypeError: S.startsWith is not a function
    at Va

and it references this line.

Any thoughts on how to proceed?
