Black screen

[Nieox]

Hello!

As soon as I pasted the code in the modules array and saved the MM refreshed (as aspected) but after that I only get a black screen with the cursor in front of it.
No error, no other modules. Just a black screen with the cursor.

For the setup I have not deviated from the guide.

Has anyone an idea what went wrong?

EDIT: If I put all the modules lines in comment ( // ) MM is displaying just fine.

Hi! I have the same symptoms. After adding this module to my config and restarting MagicMirror, it crashes.

The pm2 error logs show the following:

Any idea what I could be doing wrong?

If you need any other info, please let me know. Thank You!!
:-)

PS:
This is what I added to my config:

	{
			module: 'MMM-iFrame-Ping',
			position: 'bottom_right',	// This can be any of the regions.
			config: {
				// See 'Configuration options' for more information.
				url: "http://192.168.0.100:8080", //url to display
				height:"100%", 
				width:"100%",
				autoRefresh: true, //set to false for video
				updateInterval: 1, //in min. Only if autoRefresh: true
				displayLastUpdate: true,
				width: "100%", // Optional. Default: 100%
				height: "400px", //Optional. Default: 100px
				scrolling: "no" 
				}
		},

Hi @flo269, @Nieox, and anybody else who comes across this in the future (you may have web-searched for "cannot find module 'request'" and "mmm-iframe-ping")!

The documentation is lacking one essential step, the installation of required modules. After cloning the mirror module you need to run npm install in the module's directory. The whole installation instruction should read:

cd ~/MagicMirror/modules
git clone https://github.com/AgP42/MMM-iFrame-Ping.git
cd MMM-iFrame-Ping
npm install
