fish: 'node --experimental-wasi-unstab…' terminated by signal SIGABRT (Abort)Repro code:

const fs = require('fs');
const { WASI } = require('wasi');
const wasi = new WASI({
args: process.argv,
env: process.env,
preopens: {
'/sandbox': '/not/real/path'
}
})I think maybe we can add some pre-check here ? The current error message doesn't provide much information.
