Error 200 - Bridge response error, please check the API docs or this ajax response

[curiousPup]

I get this error while listing the files.
Line 18 in filenavigator.js
It is successful call with response code 200 but the type of data in response is a string instead of object (as expected).
String contains the content of AngularFileManagerServlet.java
