I'm getting this error:

I basically wanted to make an annoying ESM-only module synchronous:

var done = false;
var data;

let _module = import('franc');

_module.then(result => {
    data = result;
    done = true;
}).catch(err => {
    done = true;
})

require('deasync').loopWhile(function(){return !done;});

I am having the same problem with Node 20 and Node 21.
