I have a question please

by mistake, I have removed the node so when I deploy the code it gives me this message Error: node not deployed.
is there undo command?

If you haven't deployed morethan once, there is a backup flow. But why don't you just add the node back in?

I will add the node back and well see mate

Exactly what did you do to get into this situation? Knowing that may help us get you out of it.

That's more than one node it looks like you removed.
