Can not read generated file with layer style. TypeError: Cannot read property 'MSAttributedStringColorAttribute' of undefined

[Koshub]

Hello. Reading generated file with a shared layer style produces an error.

if (fs.existsSync(path)) {
  Sketch.fromFile(path)
  .then(sketch => {
    console.log(sketch)
  })
  .catch(error => console.log(error))    
} else {
  const sketch = new Sketch()
  sketch.addLayerStyle({
    name: 'Test Layer Style',
    fills: [
      {
        color: '#008AE7'
      }
    ],
    borders: [
      {
        color: '#859099'
      }
    ]        
  })
  sketch.build(path)
}

Error on reading:
