Nodered error after moving to openHAB3

[vavo01 (Valentin Voth)]

found the right hint here. Now node-red runs again like a charm.

Node-Red on OH3

Correct! I managed as well to get it working. Steps taken: from openhabian install nodered including openhab specific nodes create an api token in OH, use this as username in the config node done! If not, check you are on version 1.1.8 from the OH node (you can find this in the pallette). If not, reinstall nodered from the openhabian menu.
