Is Octo not enabled ? Help!

When I enable Octo in jicofo/rootfs/defaults/sip-communicator.properties
org.jitsi.jicofo.BridgeSelector.BRIDGE_SELECTION_STRATEGY=RegionBasedBridgeSelectionStrategy
#org.jitsi.jicofo.BridgeSelector.BRIDGE_SELECTION_STRATEGY=SplitBridgeSelectionStrategy

i get the following error for either option that I enable

same error here, did you resolve it?

I was using jitsi docker. I updated to the latest version and the error went away.
What version of jitsi/jicofo are you on ?

latest unstable, linux setup…
I have shared my configs in Testing Octo Setup , may be you can see what is missing
