Code To Reproduce Issue

public enum FeatureDetector {
    AKAZE, AGAST, BRISK, FAST, GFTT, KAZE, MSER, SIFT, ORB
}

FeaturesMatchingResult result = driver.matchImagesFeatures(bytesSrc,
                                     bytesTemp,
                                     new FeaturesMatchingOptions()
                                             .withDetectorName(FeatureDetector.AKAZE)
                                             .withGoodMatchesFactor(40)
                                             .withMatchFunc(MatchingFunction.BRUTE_FORCE_HAMMING)
                                             .withEnabledVisualization());

Unfortunately opencv4nodejs seems to be abandoned for quite a while and I don’t think I could help much with that. Maybe there are some C++/Node experts around who could help you to make it working. Appium is also just a client to this library
