Ich bekomme INVALID_ARGUMENT, wenn ich versuche, Google Cloud Vision

Question

zu verwenden. Also möchte ich nur Text oder Etiketten aus einem Bild mit der Google Cloud Vision API erkennen. Aber wenn ich diesen Code ausführen ich immer bekommen: com.google.api.client.googleapis.json.GoogleJsonResponseException: 400 Bad Request

Aber ich weiß nicht, warum ... hier ist die volle json Ausgang, was ich bekommen:

{ 
    "code": 400, 
    "errors": [ 
    { 
     "domain": "global", 
     "message": "Request Admission Denied.", 
     "reason": "badRequest" 
    } 
    ], 
    "message": "Request Admission Denied.", 
    "status": "INVALID_ARGUMENT" 
} 

Mein Testcode ist hier:

    @Override 
    String detect(String filePath) { 
     HttpTransport httpTransport = new NetHttpTransport(); 
     JsonFactory jsonFactory = GsonFactory.getDefaultInstance(); 

     Vision.Builder builder = new Vision.Builder(httpTransport, jsonFactory, null); 
     builder.setVisionRequestInitializer(new 
       VisionRequestInitializer(CLOUD_VISION_API_KEY)); 
     Vision vision = builder.build(); 

     BatchAnnotateImagesRequest batchAnnotateImagesRequest = 
       new BatchAnnotateImagesRequest(); 
     batchAnnotateImagesRequest.setRequests(new ArrayList<AnnotateImageRequest>() {{

      File imgPath = new File(filePath); 
      try {

      WritableRaster raster = bufferedImage.getRaster(); 
      DataBufferByte data = (DataBufferByte) raster.getDataBuffer(); 

      byte[] imageBytes = data.getData();

      base64EncodedImage.encodeContent(imageBytes); 
      annotateImageRequest.setImage(base64EncodedImage);

      annotateImageRequest.setFeatures(new ArrayList<Feature>() {{

       labelDetection.setMaxResults(10); 
       add(labelDetection); 
      }}); 

      // Add the list of one thing to the request 
      add(annotateImageRequest); 
     }}); 

     Vision.Images.Annotate annotateRequest; 
     BatchAnnotateImagesResponse response = null; 
     try { 
      annotateRequest = vision.images().annotate(batchAnnotateImagesRequest); 
      // Due to a bug: requests to Vision API containing large images fail when GZipped. 
      annotateRequest.setDisableGZipContent(true); 

      response = annotateRequest.execute(); 
      System.out.println(response.toString()); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 

     return convertResponseToString(response); 
    } 

    private String convertResponseToString(BatchAnnotateImagesResponse response) { 
     String message = "I found these things:\n\n"; 

     List<EntityAnnotation> labels = response.getResponses().get(0).getLabelAnnotations(); 
     if (labels != null) { 
      for (EntityAnnotation label : labels) { 
       message += String.format("%.3f: %s", label.getScore(), label.getDescription()); 
       message += "\n"; 
      } 
     } else { 
      message += "nothing"; 
     } 

     return message; 
    } 
} 

Also die Frage ist .. was ist falsch mit diesem Code?
