unable to get keypoints in opencv.js by orb detect and compute.

here is the code

*let orig = cv.imread(canvasOutput1); let temp = cv.imread(canvasOutput2); var orb = new cv.ORB(10000); let des = new cv.Mat(); let img3 = new cv.Mat(); var noArray1 = new cv.Mat(); var kp1 = new cv.KeyPointVector(); // find the keypoints with ORB orb.detect(orig, kp1, noArray1); // compute the descriptors with ORB

var das=new cv.Mat();   
orb.compute(orig, kp1, das);

   console.log(kp1);              //the keypoint vector is not showing any keypoints like python
for (i=0;i<kp1.size();i++)
{
    console.log(kp1[i].pt);              //this is giving error when trying to print points.
}*
