Using ZoneName variable with assign rule for notifications

Icinga Web Modules Icinga Director

Hello, I’m trying to set up notifications to be sent from satellites.

As suggested in this comment, I’m setting the assign rule as following in Director:

assign where ... && host.zone == ZoneName

The issue is that Director is adding quotes around the ZoneName variable which renders the rule useless:

assign where host.address && host.zone == "ZoneName"

Is there a way of avoiding this behaviour?

Thanks!
