Troubleshooting Tip: An error creating CMDBError on HA settings

[Ted]

Description	This article describes how to troubleshoot when the CMDBError message regarding HA settings occurs like 'The error creating CMDBError: Expected response argument to be an object or string,get null'. If FGSP is reverted to FGCP without unsetting 'standalone-config-sync', the CMDBError message occurs on the GUI as below.
Scope	FortiGate.
Solution	Run a CLI command below to check if HA settings to perform FGCP are set correctly.  # show system ha    # config system ha     set group-id <id>     set group-name <name>     set password ENC <password>     set hbdev <port1> 100 <port2> 100     set standalone-config-sync enable <----- Needs to unset the config.     set override disable     set priority <priority>     set monitor <port1> <port2>     end If the 'standalone-config-sync' is enabled, it is not possible to revert to FGCP, so it is necessary to unset the config in order for the unit to be inserted into a HA cluster.
