Hi Kordian,
did you try running the service in IS Admin?
Packages > Management > WmRoot > Browse Services > wm.server.triggers:getTriggerReport
In the output you will find the structured values.
As this is an internal service, it has no public documentation and may change without notice. Therefor it has no output signature (in this case), but the objects exist in the output pipeline of the service.
Regards,
Holger
