importing template error - Field "parent_itemid" cannot be set to NULL.

[cvee.it]

While trying to import "Template_Net_Cisco_SNMPv2_3.4.5.xml" https://share.zabbix.com/network_dev...-net-cisco-ios I received the error below.
This is an upgraded Zabbix from 3.2 Centos 7, to a new server running/upgraded to 3.4.9 on Centos 7.

I know/pretty sure this works without issue on new implementations, but via my current upgrade path at this client received the below.
All templates from the module pack from zabbix share have been imported. https://share.zabbix.com/official-te...e-modules-pack


Error:

I do have similar errors with different offset and line numbers.

what I found out that it is somehow related to Discovery (well, actually in all error messages does processDiscoveryRules() exist). If I disable Discovery rules in the import page then it imports without error.

So FYI

I worked around the problem by exporting the individual templates within the cisco import that was failing from a new install instance i have at home.
Individually importing the cisco templates was successful. Then when I retried the original template that was failing, there was no error.

Hope that helps someone in the future.
