Preprocessors creates originalErr

online are some fixes for my problem but I didnt get any to run. My problem is, that every time I add the preprocessors to my karma.conf.js I get a originalErr but otherwise I get a require is not defined error.

Here the karma.conf.js with the preprocessors: module.exports = function(config) {

var appBase     = 'app/';
var backBase    = 'backend/';
var cssBase     = 'css/';
var testBase    = 'test/';

config.set({
    basePath: '.',
    frameworks: [ 'jasmine' , 'browserify' ],
    browserify: {
        watch: true,
        debug: true
    },
    preprocessors: {
        'test/**/*.ts': [ 'browserify' ]
    },
    plugins: [
        'karma-browserify',
        'karma-jasmine',
        'karma-coverage',
        'karma-chrome-launcher'
    ],
