worker sent an error! undefined:undefined: undefined

[erjoalgo]

Hello,

I'm trying the example server.js, when I navigate to http://localhost:9091/, all I see is:

worker sent an error! undefined:undefined: undefined

When examining the exception in the debugger, the onerror argument doesn't appear to contain any error message, other than type: 'error':

How do I get a more meaningful error message to help debug this further?

I'm running server.js as node server.js

After some debugging, I found that the _scriptName is undefined, and the new Worker(...) was being passed an undefined script name:

There is an attempt to define it in the snippet below, but both the document and __filename are undefined in my browser:

var _scriptName = typeof document != 'undefined' ? document.currentScript?.src : undefined;
if (typeof __filename != 'undefined') _scriptName = _scriptName || __filename;

After hard-coding the _scriptName, I get another, more interesting error:

if (!_scriptName) {
  _scriptName = "/src/stockfish.js"
  // throw new Error("undefined _scriptName!");
 }

Stockfish 16.1 WASM Multithreaded by the Stockfish developers (see AUTHORS file)
worker sent an error! http://localhost:9091/src/stockfish.js:38: Uncaught RuntimeError: memory access out of bounds

I am beginning to wonder whether I'm missing something important about running the examples, or whether the examples are up-to-date with the latest code since I'm facing several issues.
