No Dashboard after Upgrade


I m using openhabian on a raspi device. After Upgrading to Openhab3 i upgraded node-red too (using the script) and even the nodes.
Now the Dashboard is still blank (Please add some UI nodes to your flow and redeploy.) Any idea ?

Is it showing the flows ok?

Please stop node-red and start it again in a terminal and post the full script you see in the terminal.

Hi flows showing ok, they work.

Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

okay i think i did it

node-red (or something else using port 1880) is already running.
Stop that then try again (on a PI that would be node-red-stop)

Dont worry about these for now - easily fixed (RBE node replaced by the Filter node)

First was npm init to create package.json...

Finally i used to reinstall all dashboard related nodes. Now everything is working fine.
