I've been using the Large-Image withe Node-Red for a long time now and previously been able to Reboot or Shutdown my RPi using and Exec node. For Reboot the command has been "reboot #" and "poweroff #" to shutdown.
I have just noticed that neither command now works with an Error: 126. Is there a new command? Is this a permissions thing?
It's all worked so well for so long I've only needed to do updates so perhaps missed some changes. Thanks for any info.
