HTTP 400 on msg.read() (sometimes)

[truenicoco]

Marking a message as read sometimes raise a 400 response from PUT.

I did not manage to understand exactly when or why it happens, but it is not uncommon at all

Steps to reproduce

from threading import Thread

import skpy

def skype_blocking():
    while True:
        for event in sk.getEvents():
            print(event)
            if isinstance(event, skpy.SkypeNewMessageEvent):
                if event.msg.userId != sk.userId:
                    print(event.msg)
                    print("Attempting to mark it as read")
                    event.msg.read()

sk = skpy.Skype(user, pass)

Thread(target=skype_blocking).start()

input()  # just to keep the thing going
# then wait for a few messages, since it does not happen all the time...

Can you find the corresponding call in your browser's network request history when you read a message in Skype for Web? If it's inconsistent then that horizon value likely isn't being generated correctly.

[truenicoco]

Sorry for not getting back to this earlier. I would be happy to help debug this, but it's a bit tricky because after using the skpy client, it seems that messages sent to me are automatically, instantly marked as read as soon as they are sent. So the horizon value thing sounds like a plausible theory to me, ie, maybe skpy sends "I have read up to sometime_in_the_future" at some point; the fact that it does not happen all the time is weird though.

Feel free to add me on skype (same handle as here) if you want to test it out in case we manage to be available at the same time.
