I checked sdnc Karaf logs, and it looks OK and no special error to the preload I did. I bounced sdnc-sdnc-0 pod and now I'm not getting the message "No preload data found to match vnf-name" when I instantiate the VF-Module from VID.
I can see from Multicloud logs that, SO is now able to reach Multicloud broker which calls multicloud-k8s plugin to instantiate the infra workload in the far edge.
Now I'm facing some connectivity issue between the two edges and once it is fixed I will resume the testing and let you know.
