Within Raspberry Pi command prompt (and through Putty since I made it so that I can control the Raspberry Pi from any device) I can run the command "fswebcam yourimage.jpg" and it makes a picture with the plugged in webcam (it's something I had to install & it works). However, when I try run this same command through a Node-RED exec node, I can't get it to work. Know that this is my first time working with Node-RED so I might just be missing something. I installed Node-RED on the Raspberry and I'm at a loss. I'm first using an inject node to activate the command, then it's linked to the command "fswebcam yourimage.jpg" and after that there's a debug node. It keeps saying "node has undeployed changes" and doesn't work. (note: after this I need to make it so that there's a node that will recognize if there's a face in the taken picture, but right now it doesn't even make the picture so I'm focussing on that)
