KeyError: 'dataset'

On adding a custom voice, the Piper Addon in Home Assistant throws this error:

Traceback (most recent call last):

The voice is recorded using Piper Recording Studio, and trained using the Pyhton Piper Train module. Exported to onnx as per the documentation here: https://github.com/rhasspy/piper/blob/master/TRAINING.md

I realize this may be too little data to draw a conclusion, but if anyone has a pointer in the right direction...

I've just updated the preprocessing script to add the necessary pieces. You will need to add/merge these fields manually in to your config for now:

{
  "dataset": "<name of your voice>",
  "audio": {
    "quality": "<x_low/low/medium/high>"
  },
  "language": {
    "code": "<example: en_US>"
  }
}
