[EnergyPlus_Support] Return Air Bypass

Hi,

I am trying to install a return air bypass in a single zone HVAC system. I first created the system using a template, but now I'm working in the expanded idf. I've been comparing my model to an example one, but for some reason I keep getting the errors below. Am I missing something when it comes to connecting an inlet node to an outlet node between two branches?
