json - Bluemix Visual recognition service working with curl command for custom classifiers but returning result for default classifer with node application -

i trying visual recognition service, trained sample images , created custom classifier. when testing curl command working fine , returning result classifier mentioned in params.json. same not working node application, seems neglecting params.json while processing. params.json

{"classifier_ids": ["<classifierid>"] } 

curl command working.

curl -x post -f "images_file=@virt.jpg" -f "parameters=@params.json" "https://gateway-a.watsonplatform.net/visual-recognition/api/v3/classify?api_key=<api_key>&version=2016-05-20" 

below node application code returns result "default" classifier

var visual_recognition = new watson.visualrecognitionv3({   api_key: 'api_key',   version_date: '2016-05-20' });   var params = {   images_file: fs.createreadstream('virt.jpg'),   parameters: fs.readfilesync('params.json'), }; 

even tried 1. putting threshold 0.0 params.json 2. using json.stringify on parameters.

it returing resilt default classifer.

any help/suggestion highly appreciated.

thanks, vishwas

this got resolved adding classifier id in params images_file

var params = {images_file: fs.createreadstream('image.jpg'),classifier_ids:[ "classifier_id" ]}; 

seems documentation misleading or there way pass classifier ids.
