Can not fetch req_body

Hi,

I have some issue fetching the body of a request.

I tried to come up with a fix, but I got lost between fetch, aspect, body, req_body and raw_req_body. :cry:

So, I could not come up with anything better than a failing test. I would be glad to help fixing up this issue, but I would need some guidance. :nail_care:

Hope this helps!
