Firze's answer is correct but here is a more elaborated answer. I am not allowed to comment so I am posting it as an answer.

It has to do with CodeIgniter not being able to fetch JSON. jQuery does some under the hood tricks and transforms your data into form-data-x, that's why it works when you don't specify the content type, don't encode your object, or other situations.

If you want a pure JSON the solution is to use $this->input->raw_input_stream to fetch your JSON and decode it using php's json_decode. Check the full answer and code below:
