On my node-red installation, I can't find the "exec" module in the "advanced" section, it is missing.
Is it possible to manually install this module without having to reinstall node-red?
My node-red version is v0.20.7
Hmmm. I believe the exec node is considered a core node. I do know it’s possible to deactivate it as is done on certain cloud infrastructures. Something like that can have happened on your system, but I have no idea how to accidentally trigger that. You could perhaps try reinstalling the core nodes library? @node-red/nodes
