Void product information in android IAP

Hi!
I’m using sdkbox for implementing in-app purchase on android.
after finishing all setting in both google dev console and client-side, when my app start to call sdkbox.IAP.refresh() and print ‘products’ array in ‘onProductRequestSuccess(products)’ callback,
following void product information displayed::

jswrapper: JS: [SDKBOX]:: IAP Catalog success:products=[{“transactionID”:"",“receiptCipheredPayload”:"",“receipt”:"",“price”:"",“currencyCode”:"",“description”:"",“title”:"",“id”:“item.pack1”,“priceValue”:0,“name”:“item_pack1”},{“transactionID”:"",“receiptCipheredPayload”:"",“receipt”:"",“price”:"",“currencyCode”:"",“description”:"",“title”:"",“id”:“item.pack2”,“priceValue”:0,“name”:“item_pack2”},{“transactionID”:"",“receiptCipheredPayload”:"",“receipt”:"",“price”:"",“currencyCode”:"",“description”:"",“title”:"",“id”:“ad.remove”,“priceValue”:0,“name”:“remove_ads”},{“transactionID”:"",“receiptCipheredPayload”:"",“receipt”:"",“price”:"",“currencyCode”:"",“description”:"",“title”:"",“id”:“slime.large”,“priceValue”:0,“name”:“slime_large_pack”}

could anyone help me?

solved by No product data when calling sdkbox.IAP.refresh() on Android ?
