I’ve started receiving this message today after updating the nodes after what I assume was an update to Node Red. Does anyone know what this is all about and how to rectify it. I thought base URL was deprecated some time back/

“Home Assistant base URL needs to be set”
got the same message after updating node-red today.
In the setting ‘Edit server mode’ I had to check the “Use The Home Assistant Add-On” option.
Now it works great again.
There were a number of HA servers there. Even when I did delete the others,. I still needed to uncheck “I Use The Home Assistant Add-On” and then check it again to stop the error from appearing.
