Have tried to reboot the system but it doesn’t change anything.
And it’s the same if I start with a new function node and try to add code, nothing happens, can’t write any code.
Anybody else that have had the same problem?
The problem is how HA calls node-red or some security it is applying. We have never seen - to the best of my knowledge - a problem like this when running Node-RED directly. (E1cid clearly has a much better memory than me! ). HA is a complex product - so complex, the recommended deployment approach is to replace your entire operating system with theirs! Node-RED is itself pretty complex but installation and configuration is simple.
