AddFilterHook not working as intended

[mandeepbrar]

I added a filter hook as follows

autogen_skipper := func(info os.FileInfo, fullPath string) error {
		if info.IsDir() && info.Name() == "autogen" {
			log.Error(ctx, "skipping autogen")
			return watcher.ErrSkip
		}
		log.Error(ctx, "not skipping ")
		return nil
}
....
w.AddFilterHook(autogen_skipper)
....
w.AddRecursive(folderToWatch);

This code skips autogen directory, however the files in the autogen folder are not skipped.

Expected behavior is that if a folder is skipped then this method should not have been called for files in the folder
