chef 12 configuration error - object not found while running knife cli - linux

Question

Running chef 12 on Ubuntu 14.1. Using self signed certs to setup the server, when I try to run knife commands from my client it fails with following error. Any operation has same error. chef server logs do not have any errors or info during the query.
knife config
