Errors Using updateHost Action in vRealize Orchestrator

[#1]

When using the Infoblox IPAM pluging 4.2.0 with vRealize Orchestrator 7.2 integrated with NIOs 8 I am encountering errors when attempting to change the host name using the updateHost action in vRO. Everything is getting into the action correctly, but I am getting back a generic error

com.infoblox.ipam/updateHost) Error in (Dynamic Script Module name : updateHost#49) An error has occurred while updating a host record. Detail: null

I verified that the account used by the endpoint was able to update the host record via REST.

I resolved the issue that I had by being sure to pass a false value for the inputs: updateHostAddress and restartIfNeeded instead of setting the to NULL.
