Cannot read local file (under node) ?

I’m trying to do a very basic thing, opening a file :

cat index.js
const jsroot = require("jsroot");

console.log("JSROOT version", jsroot.version);

jsroot
  //.openFile("https://root.cern.ch/js/files/hsimple.root") // WORKS
  .openFile("file://hsimple.root") // DOES NOT WORK
  .then((file) => console.log(file))
  .catch((err) => console.log("boum",err));

node index.js works if the file is remote but for the local case I get :

JSROOT version 6.0.0 14/01/2021
boum ReferenceError: filename is not defined

what am I missing 😉 ?
