Unable to retrieve Tincan record from Storyline output

Hi, 

We will use "storyline" to create our e-learning project and we will import the project in the Tincan API format.
I've implemented a LRS server to retrieve the information from storyline, so, I've created a rest services to get the data.
Notice that our LRS server is built with Java code.

I think that there is a problem when Storyline tries to send (post) data in the Tincan format.

The data sent by storyline has the content type 'application/json' but in reality, the data has a "application/x-www-form-urlencoded" content type and not the content type 'application/json'.

So,  I'm unable to retrieve the data using a clean way (as the HTTP standard).

The only way that I found to make it work is to retrieve the data in the body of the request (as a stream).

What do you think about it or what can I do to resolve this problem?

Thank you.
