I am working with nodered and have more than 100 nodes. Recently I wanted to use a new function node, but strangely I cannot use it because the window for editing the function does not respond on the keyboard. Also function nodes which I installed some time ago are not editable. I do not know when this problem started.
Does anyone have the same issue?
My installation of HA is 2022.08.3
Nodered V13.3.1
Start with clearing the browser cache to see if that is enough.
Then of not restart the add-on.
If that does not solve it either then restart the entire host (not just the HA core).
