Getting build id in RQM execution schedule

Hi,

an execution schedule can be set to fire on a "build finished" event from RTC if this is set up as "build provider".

I am running some automation and scripts in this execution schedule. But how do I access the build-id which kicked me off? I'm trying to pass parameters to the automation, and setting it to "${buildResultUUID}" but only the empty string is passed to the automation.

ANY help appreciated!!!
