Predictor outputs null?

[bigrig2212]

Bug description

Just wondering how the predictor works. I was thinking I was going to get data similar to the Replicate log, but i just get an occasional null - with no output at the end.

What I thought I'd get:

What I get:

Steps to reproduce

Code:

  const model = await replicate.models.get('stability-ai/stable-diffusion');
  let options = {
    prompt: req.query.phrase, 
    width: 768, 
    height: 768, 
    prompt_strength: 0.8,
    num_outputs: 1,
    num_inference_steps: 50,
    guidance_scale: 7.5,
    scheduler: "K_EULER"
  };
  //let output = await model.predict(options);

  let output = model.predictor(options);
  for await(let prediction of output){
    console.log(prediction);
  }
  
  res.status(200).json({'result':'success','data':output})
  console.log(output)
