Hi Siyuan, For PUT/POST requests, we would first have a request-response pair, following which we would do request calls with just message body till we are done with the upload file, without calling a response. So, we cannot treat NetMapIsEmpty as an error in HttpResponseWorker. I have added this description into the v2 patch I sent across.

Have you ever found any case that the TxToken is empty when trying to receive HTTP response header in the response worker? Why would that happen?
