[GeoNode-users] updatelayers not working: NoneType object has no attribute find

[Florian Hoedt]

Hello List,
Seems like this error still is present:
https://github.com/GeoNode/geonode/issues/869

I have created and deleted a lot of datastores in GeoServer (still learning) and after beeing happy with my aerials tried to:
sudo geonode updatelayers --skip-geonode-registered

which gave me:
