func_count_objs error

        // -> helper functions
        var func_count_kps = function func_count_kps(aligned_models) {
            var counter = 0;
            for (var key1 in aligned_models) {
                counter += aligned_models[key1].keypoint0.n_keypoints;
            }
            return counter;
        };

        var func_count_objs = function func_count_objs(aligned_models) {
            return aligned_models.length;
        };
        // <-
        
        I have finished setting up the Scan2CAD-Annotation-Webapp and tried running it, but I am encountering errors in the web browser. It seems there might be an issue with the coding. Could you please help explain the problem? I will create and upload a few screenshots for you to review.

Thank you.
