Hi, I have written a piece of code using C++ in order to send a PUT request (add a flow to the switch). I have used boost library in order to do this. The problem is that there is a communication between the controller and my code (Response code is 200) but the flow is not added to the controller and the switch. We have used Yang in order to add a flow and it was added successfully but when I want to add a new flow using PUT request in C++ it is not possible. There is no error and message passing between the code and controller is fine.
