Error processing event: PrintStarted

[exetico]

Hi,

I've just installed the plugin, and added the token, secured the right permissions, create the Slack-channel for it, and so on.

But after I started my printer, the following output showed up in the logs, and no info was sent to Slack:

I'm running on OctoPrint 1.4.2 with Python 3.7.3. Could it be anything related to the Python version?

Let me know if you need anything else. But I've just installed OctoPrint after updating Python, so.... There's nothing else in my installation - other than the default OctoPrint settings.

Or is it related to the vcgencmd error? My machine is a NUC, and not anything related to a Pi.

Maybe it's related to:

(Make sense....)

I'll try and disable it, and see how it goes. Maybe a logic for that part, could be included in the script?

Now I'm down to:

Fixed with: /invite @octoprint

TL;DR: Maybe add a few notes about this? Maybe I just missed that in the documentation :-) (The first part with vcgencmd could be handled a bit better in the code)
