Empty pixelData on some image layers

[davidprifti]

I have the following PSD file: https://file.io/vcH8Swxk5ffX. Some of the images get exported correctly but there are some images that fail. For example the "Rounded Rectangle" layer fails with the following error when trying to export it with saveAsPng method:

Error: Unhandled error. ('No data provided')
  at exports.PNG.emit (node:events:507:17)
  at exports.PNG.emit (node:domain:488:12)
  at exports.PNG.PNG.pack ...

After further inspection pixelData is empty on this layer.

Is this the intended behaviour? Is there any workaround for this?
