MMM-CalendarExt3 Not showing on some clients

[odin_greythorn]

Hello all,

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
					},
				},
			},

Aaaand this was it. - didn’t realize the version of chromium I was using was from two years ago.
Solved - updating chromium browser to the most recent version + reboot immediately showed the missing module. Thank you.

@odin_greythorn

more than likely it is the age of the client browser

Ext3 uses the latest JS language syntax… most older browsers do not support that
see here for more info, including a link to a browser version table

Which browser are you using in the PI? Tell us your environment exactly.

[odin_greythorn]

@MMRIZE it’s the default for onepageos, which is chromium browser. There are no custom mods to that image, it’s a stock install with the only modifications being my Wi-Fi network and the default displayed web page changed to my local server IP:port running magic mirror.

@odin_greythorn browser is for sure chromium, here is the output of chromium-browser --version:
Chromium 98.0.4758.106 Built on Raspbian , running on Raspbian 11

I need the front-end log for checking.

You can get the front-end log by;

• Ctrl+Shift+I to open front dev console on the running, or,
• npm run start:dev command, or,
• Use MMM-LogExt module to deliver front-end logs to the backend.
