Hi SivaPlease provide NSO setup details and the service payload that has the issue. I need to check the setup to debug it.Thanks,NikhilHi Siva/SagarAs discussed over the call, the nso is not setup properly in your system. Please do a re-install with correct version of NSO - 5.7.3 for M6. NC NED 7.7 is not supported for releases before M6.Let us know if the issues is resolved and we are good to close the ticket.the issue was with nso not setup properly in the system. Suggested to do a re-install with correct version of NSO - 5.7.3 for M6.
