bigiq discover of bigip ltm ve throwing following error

hi all, I am adding a BigIP LTM VE to BigIQ via discover. Its able to discover it and adds it to the list. But I saw these exceptions in the restjavad logs FYI: I had deleted the whole /root directory on BigIQ by mistake. I had deleted the restjavad config file also to recover the BigIQ. rm -rf /var/config/rest Please find the data in the link
