Greetings all. I am working through the IoT Modeling with ThingWorx program through PTC Academy and am running into issues with M6:19 Aggregator Service. Step 36 asks me to execute the "Rollup" service, but when I do, I get the error: Error executing service Rollup. Message :: TypeError: Cannot call method "GetPowerConsumers" of null - See Script Error Log for more details.
I am new to ThingWorx (obviously, since I'm taking programs through the Academy) so this could be something very easy to resolve, however, I haven't been able to figure it out. Any suggestions?
