HTTP Bad Response 400 - Githubissues

I am workig on ONVIF Camera project and I wanted to use media2 for that. I followed your repo and tried to run the examples with modification for user,pass etc

I am able to communicate to camera, and change dates, etc.

But the pullpoint pull message is giving exception and on deeper analysis - looking at packets in wireshark and log - it is receiving the packet and responding with HTTP 1.1 Bad Response. What is it that I am doing wrong?

I am attaching code/the function which is not working (all others are working) for reference :

    def subEvent(self):
        """

        该模式采用的方式：

        pullpoint = self.mycam.create_pullpoint_service()
        # print(pullpoint)
        # print(type(pullpoint))
        pullpoint = self.mycam.pullpoint.zeep_client.create_service(

            pullmsg['MessageLimit'] = 100
            try:
                pullmess = pullpoint.PullMessages(f"{pullmsg['Timeout']}", f"{pullmsg['MessageLimit']}")
                 # pullmess = pullpoint.PullMessages( 'Timeout' : "00:00:20", 'MessageLimit'=10)

                for msg in pullmess.NotificationMessage:
                    print("--" ,msg)
            except Exception as e:
                print("00000000", e)
            finally:
                pass

pullmess = pullpoint.PullMessages(f"{pullmsg['Timeout']}", f"{pullmsg['MessageLimit']}"

This statement is giving exception ( a blank one at that) and debugging the code with pycharm debugger, it shows the Bad Request 400, which I confirmed from wireshark logs.

Any Help will be greatly appreciated. as I am stuck for quite some time now. Let me know if anything else is required.
