nfs-kernel-server failed to start on debian - kubernetes

Question

A bit new to this topic and would be great if one can provide some pointers in this case:
i have been trying to use NFS on an in-house built cluster. everything worked from the link i followed except common file sharing topic.
installed NFS-kernel-server on master node
installed NFS-common on slave / worker nodes
configured /etc/exports on master node as required
configured /etc/fstab properly on worker nodes with the mount location
But unable to start nfs-server on master node and the errors show issue with the dependencies
if needed i can provide output from journalctl -xe but main error shows "Failed to mount NFSD configuration filesystem."
Any pointer / solution would be greatly helpful.
Output from journalctl -xe:
