I created another post about this that was a bit more descriptive.
See here: Looking for working example data set to bulk index into ES6
Seems I havn't solved the issue yet.
You can see a video of what I'm trying to do here:

It comes down to: I want to be able to index data and only specify the index and type. In the documentation it specifies that you don't need to specify the id each entry for a type.
The video shows step by step what I'm trying to do and the error I'm getting. Let me know if you can't open the video and I'lll just copy paste all my steps in here.
