[BUG] 8.1.0 Vision reports unknown expression function "isAuthorized"?

I’m getting this error when trying to use the Expression function isAuthorized:

ERROR com.inductiveautomation.ignition.client.util.gui.ErrorUtil - Unknown function: 'isAuthorized'

Seems like the documentation is lacking, but this is a gateway-scoped function provided by Perspective.

Is there any way to check security zone in Vision?

I don’t know if there is an equivalent… maybe someone else will. isAuthorized is about security levels, though, not zones.

In Vision I think zones are automatically applied/checked when an operation that respects zones is performed.

SecurityZones are incorporated into Security Levels though as well I think. At least that’s what it looks like in the Security Levels gateway page. I haven’t ever been able to actually use Security Zones yet though… in Vision or Perspective (I’m not getting a SecurityZone assigned to me when not logged in in Perspective)
