Unknown validation error for trapper item

[basedbulgarian]

I have a Zabbix trapper that I want to send data to. It has no preprocessing rules and it's not a dependent item. But in the Zabbix server logs I keep getting this error message: "unknown validation error for item 'vmware.log.trapper'" The trapper item is added to the VMware hypervisor template. Any ideas?

Resolved. Zabbix_sender needed to be pointed at the proxy rather than the server.
