Expected behavior When using Bundle&Minifier under Visual Studio with MDBootStrap (mdb.js), no ERROR. Using budle&minifier under Visual Studio allows to debug code when in development, and minify all the Javascripts libs into one file for production.

Actual behavior When using Bundle&Minifier, got these errors since version 4.9.0:

According to javascript, these errors are normal regarding the code. You try to assign undefined variables. Please correct these issues.
