Channel On Srf component, is it broken?

Following this GH tutorial that is using Peacock.

I’m not seeing an error , but the Channel on Srf is not working… and I have a feeling it might be related to the Sweep1 that is ATM broken on Mac. Or did I misplaced something…? [can’t find what I may have done wrong]
