Update: it looks like first three calls are intercepted by my middleware: 'negotiate', 'connect' and 'start'. They are GET so obviously there is no body.
However, right after connection is established I sending from client to server a string (e.g. POST).
For some reason, that call doesn't intercepted by middleware at all, but I do receive request inside my hub.
