We have create a discovery rule to capture Juniper SRX IPSec VPN Tunnel config state, policy name, State & Type. which was working fine in Zabbix 2.4. We upgraded our Zabbix to 3.2.7 after that I don't see the items getting created. rather getting error "Cannot create item: item with the same key "junipertunnel[]" already exists".

Please help to debug.

on the zabbix host if I do a snmpwalk, I'm getting results -

for OID 1.3.6.1.4.1.2636.3.39.1.5.1.2.1.1, which is in my discovery rule and further items as -

1.3.6.1.4.1.2636.3.39.1.5.1.2.1.1.1 Policy Name
1.3.6.1.4.1.2636.3.39.1.5.1.2.1.1.2 Type
1.3.6.1.4.1.2636.3.39.1.5.1.2.1.1.3 CfgState
1.3.6.1.4.1.2636.3.39.1.5.1.2.1.1.4 State

Even if I disable the Policy name item prototype, still no items getting created.
