basic authentication throws error

[TheLion]

Hi,

I secured my MJPEG-STREAMER stream and snapshot with a username/password. This works just fine in Octoprint and in the browser by accessing http://username:password@192.168.1.1:80/?action=snapshot. This syntax is also mentioned within the OctoSlack plugin, but when I use this syntax in Octoprint (which I suppose is used by OctoSlack) it produces an error in the log:

Not quite sure why this happens

@TheLion
Message means you supplied a string argument when a bytes argument was required.
Use 'theArgument'.encode('utf-8') to convert the string 'theArgument' into bytes b"theArgument"
Which argument? Check the docs for the failing API call.

I understand the error, but to be clear, I didn't code anything. I just entered the URL I mentioned in the box, that's it.

Thanks for reporting this @TheLion - I'll see if I can repro this setup.
Having not yet looked myself, if you have a link to the doc you followed to lock down your video stream, please pass it along as it might save me a bit of time and effort.
