Three-Nebula particle system doesn't show up?

Ok, I read here that a great three.js particle engine is https://creativelifeform.github.io/three-nebula/api/

Im trying to implement it working in node js, copied verbatim from example and no errors, but I cant see the particles at the position. To create particles I have:

particleemitter()
{

const json = {
  preParticles: 500,
  integrationType: 'euler',
  emitters: [
    {
      rate: {
        particlesMin: 5,
        particlesMax: 7,
        perSecondMin: 0.01,
        perSecondMax: 0.02,
      },
      position: {
        x: 0,
        y: 1,
      },
      initializers: [
        {
          type: 'Mass',
          properties: {
            min: 1,
            max: 1,
          },
        },
        {
          type: 'Life',
          properties: {
            min: 2,
            max: 2,
          },
        },
        {
          type: 'BodySprite',
          properties: {
            texture: './src/images/glow.png',
          },
        },
        {
          type: 'Radius',
          properties: {
            width: 8,
            height: 8,
          },
        },
      ],
      behaviours: [
        {
          type: 'Alpha',
          properties: {
            alphaA: 1,
            alphaB: 0,
          },
        },
        {
          type: 'Color',
          properties: {
            colorA: '#4F1500',
            colorB: '#0029FF',
          },
        },
        {
          type: 'Scale',
          properties: {
            scaleA: 2,
            scaleB: 2,
          },
        },
        {
          type: 'Force',
          properties: {
            fx: 0,
            fy: 0,
            fz: -20,
          },
        },
      ],
    },
  ],
};

const system = new System.fromJSONAsync(json, THREE).then(console.log);
//this.scene.add(system);

}

And the particle system is printed to the console. I placed another object at (0,1,0) and I can see it, just not the particle system. Whats wrong?
