In the files section under my call there is a readme file which outlines nodes needed for my flows. Those nodes were not installed. The file also includes instructions on how to install the nodes.
In the first example, it appears you are not hitting the "Deploy" button after you make a change.
In the second example, you have missing "Nodes". ?Node-Red does not install the "Dashboard" nodes, so you need to add them.
Go to the pull down on the upper right, select "Manage Pallet". ?On the "Install Side", enter a search name for the missing pallets, in this case "dashboard". ?You will see a section below. ?In your example, select the "node-red-dashboard" and hit "install". ?Be careful not to select the "cn-dashboard-nodes"
As you import new flows, Node-Red may say you have additional missing Nodes. ?Make a note of their name and add them in the same manor.
