MMM-Wallpaper gives black screen on one MM. Other one works.

[Cliff365]

The script is identical on both. It works on one, but other gives me a black screen with just a cursor. I have tried bing and chromecast sources and still a black screen.

{
			module: "MMM-Wallpaper",
				// git clone https://github.com/kolbyjack/MMM-Wallpaper.git
				position: "fullscreen_below",
				config: { 
				// See "Configuration options" for more information.
					source: "chromecast",
					slideInterval: 30 * 500 // Change slides every 30 seconds
				}
		},

@Cliff365 show the output from npm start

and also open the developers window, ctrl-shift-i on the mm window,
select the console tab and enter wall in the filter field

@Cliff365 im guessing it this

if (typeof(fetch) === “undefined”) {
fetch = require(“fetch”);
}

on the system that fails, (black screen) do

node -v

i bet its less than 18…

[Cliff365]

@sdetweil Thanks, I will take a look.

[Cliff365]

@sdetweil Where would that code go? Command line?

Node -v returns 16.19.0.

Do you know the command to update node?

[sdetweil]

@Cliff365 best thing to do is run my upgrade script

see

@sdetweil Thanks! I ran the script, and it’s been sitting at this for about an hour. I assume I should just reinstall MM.

[sdetweil]

@Cliff365 no. maybe get out?

try this

sudo apt-get -y remove nodes npm

then node -v

the npm install was supposed to be done in the module folder

On my system before Wallpaper was updated as well, I did a npm install fetch in the module directory to get it back.

might be worth a shot.

@sdetweil said in MMM-Wallpaper gives black screen on one MM. Other one works.:

sudo apt-get -y remove nodes npm

I think that did the trick. Thanks! node now reports v20,5,1

[sdetweil]

@Cliff365 sorry typo in command, my phone thought it knew better!!!

sudo apt-get remove nodejs -y
