Colin,
You're king! I followed your steps: installed node.js v.14.x, rebuild npm and uala....tado node started working immediatelly...
Thank you so much!
Maybe one additional question not related to intiial question.
In previous version of nodered, I was used to use shortcut ctrl+Right click to get most used nodes...in v.2.2. This is not working anymore. Any idea if this is possible through any other command?
