Gulp running error

[bostrot]

Hi there, I am encountering a gulp error when trying to run the gulpfile.js with your example code.

sudo gulp
[19:28:18] Using gulpfile /home/pi/CarData/Gulpfile.js
[19:28:18] Starting 'default'...
[19:28:19] Finished 'default' after 38 ms
/home/pi/CarData/node_modules/xml-stream/lib/xml-stream.js:430
    container[container.length - 1] = val;
                        ^

TypeError: Cannot read property 'length' of undefined
    at Parser.<anonymous> (/home/pi/CarData/node_modules/xml-stream/lib/xml-stream.js:430:27)

    at Readable.read (_stream_readable.js:475:10)
    at flow (_stream_readable.js:846:34)

gulpfile.js contains

var gulp = require('gulp');
var converterTjs = require('gulp-converter-tjs');

gulp.task('default', function () {
gulp.src('./cascade.xml')
    .pipe(converterTjs())
    .pipe(gulp.dest('./modified-files'));
});

gulp and gulp-cli are both on the latest version. has anyone encountered the same error before and know how to fix it?
