ngCordova camera

Hi I have a problem with the camera.

To provide my app with data I use a socket based database similar to Firebase and it works just fine.

And what I want to add is the ability to take a picture and upload that so I add the file, camera and file-transfer plugins, and after that no data is showing in my app anymore, and as soon as I remove them again it works..

I get this error

TypeError: reader.addEventListener is not a function. (In 'reader.addEventListener('loadend', onLoadEnd, false)', 'reader.addEventListener' is undefined)
blobToBufferrethinker.js:6127
onmessage

Could there be some kind of conflict?
