Unable to execute "fibonacci" demo by using napa

[SwenChan]

environment: macos 10.13.5
node: 10.6.0
napajs: 0.2.3
code

const napa = require('napajs');
const zone = napa.zone.create('zone', { workers: NUMBER_OF_WORKERS });
function fibParallel (n) {
      if (n <= 1) {
        return n;
      }
      var p1 = zone.execute('', 'fibParallel', [n - 1]);
      var p2 = zone.execute('', 'fibParallel', [n - 2]);
      var p3 = zone.execute('', 'fibParallel', [n - 3]);
      var p4 = zone.execute('', 'fibParallel', [n - 4]);
      // Returning promise to avoid blocking each worker.
      return Promise.all([p1, p2, p3, p4]).then(([result1, result2, result3, result4]) => {
        return result1.value + result2.value + result3.value + result4.value;
      });
    }
zone.broadcast(`
    var napa = require("napajs");
    var zone = napa.zone.get("zone");`);
    // Broadcast function declaration of 'fibonacci' to napa workers.
    zone.broadcast(fibParallel.toString());
const num = await zone.execute('', 'fibParallel', [30]);
console.log(num)

And it throw

I'm also facing the same.

@SwenChan did you find any solution for that? , I know it's almost 3years back you posted this, but I hope you have some information, As i need a multi-thread feature in my nodejs application, Trying different available ways to fix.. My Node version 10.16.3
