I’m new to magic mirror but somewhat experienced with linux/rpis. I’m running magic mirror in docker on a linux server as a host and attempting to build a little station as a client with a raspberry pi 3 b+. Why? I already had the server up and wanted to just use the pi as a client in hopes that it would run faster.
I have the host service up and running how I’d like it (default calendar module with 4 google calendars, MMM-CalendarExt3, MMM-BackgroundSlideshow, default clock, default weather module current + forecast).

So my issue is that when viewing the hosted page on any PC or mobile device, I can see my configured MMM-CalendarExt3 module perfectly, but when viewing from the pi, it’s not there. Everything else loads and displays properly except for the monthly calendar view.
The pi setup is a bit weird - I am running fullpageos as the image (based on bullseye I think) and the attached display is a salvaged laptop screen with an ebay display driver board. I couldn’t get regular kiosk mode to work at all for this setup, which prompted me to try out this image.

Here’s my module config for CExt3, and I don’t see any issues in the logs, but I can post that too if more info is needed. I have also tried commenting out every module except for CExt3 and using the fullscreen_above position to be sure there wasn’t any interference and I still got nothing showing for the pi

{
				module: "MMM-CalendarExt3",
				position: "bottom_center",
				title: "Family Calendar",
				config: {
					weekIndex: 0,
					useMarquee: true,
					weeksInView: 3,
					eventTransformer: (ev) => {
						if(ev.calendarName === 'Birthdays') ev.color = 'darkorchid'
						if(ev.calendarName === 'Holidays') ev.color = 'black'
						if(ev.calendarName === 'me') ev.color = 'seagreen'
						if(ev.calendarName === 'wife') ev.color = 'navy'
						return ev
					},
				},
