Issue with broken dep

browserify、brfs、reactify、factor-bundleを使用するgulpfileのパイプラインから始め、viewer.htmlによって読み込まれる生成済みのcommon.min.jsとmain.min.jsを調査します。Chrome拡張機能のエラーを再現し、失敗しているモジュール参照の行を追跡します。factor-bundleの出力がundefinedプロパティエラーなしで読み込まれ、以前のbundle.min.jsの動作に置き換われば完了です。

I am using browserify with brfs in a Chrome extension. My gulpfile looks like this:

gulp.task('browserify', function() {
  return browserify(paths.main)
    .transform(reactify)
    .transform({global: true }, 'brfs')
    .plugin('factor-bundle', {outputs: ['build/main.min.js', 'build/background.min.js']})
    .bundle()
    .pipe(source('common.min.js'))
    .pipe(gulp.dest('build/'))
})

In the bundle loaded into the Chrome extension, I have a viewer.html page, into which I have plopped:

<script defer src="../../common.min.js"></script>
<script defer src="../../main.min.js"></script>

In place of the previously working bundle.min.js. Now, however, on load, main.min.js no longer works, throwing a Uncaught TypeError: Cannot read property '0' of undefined error. The line it points to looks like this:

{"react/lib/ExecutionEnvironment":682,"react/lib/invariant":788}],280:[function(require,module,exports){
arguments[4][278][0].apply(exports,arguments)
},

I'm afraid I have no idea why this is happening, at all, to the point of not knowing how to even name this issue. I'm going to go back to not using factor-bundle for now. I'll have keep this issue in a branch, but I'm stumped.
