Thanks for letting us know about this. I just tried the same and Burp correctly showed the request body. "Screenshot":https://imgur.com/a/aK7v5XN This is Python 3.6.6 with Requests 2.19.1 on Windows 10. If you could explain a bit more about what you've done and you Python, OS and Requests version, that would help us reproduce this.

I am on burp v1.7.36 build 56 but I have tried multiple versions. I am running ubuntu 18.04, python 3.6.6, requests 2.19.1. I have tried openjdk8/10, oracle jdk8 for running burp all showed the same error. I am setting the proxy using export https_proxy=http://127.0.0.1:8080 I am only seeing this on http requests that, and put and post work fine. everything else does not send the body. libssl-dev is already the newest version (1.1.0g-2ubuntu4.1). I don't see the issue in python2.7 but in 2.7 python seems to make only one connection and send the entire stream and in python 3.6.6 it is sending the body separately. The request works as expected on zap and postman. Screenshot of the issue. https://imgur.com/a/mGVYoBL After a log hang I get a ConnectionResetError: [Errno 104] Connection reset by peer During handling of the above exception, another exception occurred: ProtocolError: ("Connection broken: ConnectionResetError(104, 'Connection reset by peer')", ConnectionResetError(104, 'Connection reset by peer')) During handling of the above exception, another exception occurred: ChunkedEncodingError: ("Connection broken: ConnectionResetError(104, 'Connection reset by peer')", ConnectionResetError(104, 'Connection reset by peer'))
