failure in exporting an annotated .ply

[Coldplayplay]

open the link http://localhost:8010/scans/segment-annotator-single?condition=manual&userId=username&taskMode=new&modelId=my_data.bunny

after annotating the .ply, I failed in exporting the annotated .ply as the instructions say in https://github.com/smartscenes/sstk/wiki/Semantic-Segmentation-Labeler

PS. I copied the example nyuv2.json and changed something. My complete my_data.json is as follows.

{
    "source": "my_data",
    "assetType": "scan",
    "rootPath": "${baseUrl}/data/my_data/my_asset",
    "screenShotPath": "${rootPath}/${id}/${id}.png",
    "hasThumbnail": false,
    "assetFields": ["segment-annotations-manual", "scan-model-alignments"],    
    "formats": [
      { "format": "ply",
        "path": "${rootPath}/${id}/${id}.ply",

        "materialSidedness": "Front",
        "useVertexColors": true,
        "computeNormals": true
      }
    ],
    "surfaces": {
      "format": "segmentGroups",  
      "file":  "${rootPath}/${id}/${id}.segs.json"
    },
    "segment-annotations-manual": {
      "format": "segmentGroups",
      "files": {
        "annIds": "${baseUrl}/scans/segment-annotator-single?condition=manual&userId=username&taskMode=new&modelId=${fullId}",
        "segmentGroups": "${baseUrl}/scans/segment-annotations/aggregated?annId=${annId}",
        "segments": "${rootPath}/${id}/${id}.segs.json",
        "annotatedAssetIds": "${baseUrl}/scans/segment-annotations/list?$columns=itemId&format=json&condition[$in]=manual"
      }
    },
    "scan-model-alignments": {
      "files": {
        "annIds": "${baseUrl}/annotations/list?itemId=${fullId}&$columns=id,workerId,data&format=json&type=scan-model-align&condition[$in]=manual",
        "annotatedAssetIds": "${baseUrl}/annotations/list?$columns=itemId&format=json&type=scan-model-align&condition[$in]=manual"
      }
    }
  }

use ssc/export-annotated-plys.js

NODE_BASE_URL=http://localhost:8010 ./export-annotated-ply.js --id bunny  --source my_data --ann_type raw -n 1 

Errors are here:

I just wanna use this tool and really don't know about how to code with nodejs, having no solution, so hope for your suggestions. Best wishes. BC Chen

The problem is most likely due to a mismatch between the --ann_type raw argument and the specified surfaces type in the json file (there is only the segment-annotations-manual type there). Try running with --ann_type segment-annotations-manual instead and let us know if that shows any errors.

@msavva I tried running with --ann_type segment-annotations-manual.

NODE_BASE_URL=http://localhost:8010 ./export-annotated-ply.js --id bunny  --source my_data --ann_type segment-annotations-manual -n 1 

Result is as below.
