MORPH_HITMISS seems to be not correct when used with morphologyEx

Hi, I'm a newbie trying to learn opencv4nodejs. I refer to the tutorials on opencv.org to learn. I'm facing an issue with "Hit or Miss" based on https://docs.opencv.org/4.1.2/db/d06/tutorial_hitOrMiss.html . I always get blank image with any kernel with this usage:
output_image = input_image.morphologyEx(kernel, cv.MORPH_HITMISS);

It seems cv.MORPH_HITMISS is not correct. Please help to check.
Opencv4nodejs version 5.5.0 on Windows 10
