What happened?

Here is the style.json file code:

{
  "version": 8,
  "name": "osm_tianditu",
  "metadata": {"maputnik:renderer": "mlgljs"},
  "sources": {
    "osm_amap": {
      "type": "raster",
      "tiles": [
        "https://webst01.is.autonavi.com/appmaptile?style=6&x={x}&y={y}&z={z}"
      ],
      "minzoom": 0,
      "maxzoom": 14,
      "scheme": "xyz",
      "tileSize": 256
    }
  },
  "sprite": "",
  "glyphs": "https://orangemug.github.io/font-glyphs/glyphs/{fontstack}/{range}.pbf",
  "layers": [{"id": "amap", "type": "raster", "source": "osm_amap"}],
  "id": "67f7gnk"
}

When i use this style.json and use OfflineRegion's download function.
It can download but it will always be stuck at the last 4th resources.
It is normal to use https://americanamap.org/style.json.
Can you help me?
Thanks.

Steps to reproduce

Use the style.json and download OfflineRegion
