IPS - SCIM API V2 filter users by user group assignment

[MarcoDebattisti]

Hi, we have a requirement to filter out users in the IPS sync that belongs to a specific User Group in SF.

e.g.: users assigned to user group "GG-IASSYNC" should NOT sync to IAS.

In the Source system properties, we set up sf.group.filter with value displayName ne "GG-IASSYNC".

While in the Target transformation we added this condition: && ($.groups[?(@.displayName == 'GG-IASSYNC')] EMPTY true)

We are using sf.api.version 2, but the condition above does not seem to work.

How can we write that condition or how can we filter out ousers based on their user group?

Thanks

Marco
