Error: Define Overland Preferential Node Link Schema

I'm working through an ArcHydro workflow and just ran the Connect Control Structure Junctions tool. The workflow I'm using was developed by a coworker for ArcMap and we are adapting it as we go. When I run the DOPNLS tool, I get a few errors that I don't know how to address (pictured). I've attached screenshots of my inputs and results. I'm not really sure what else I can do besides keep running the tool and hoping for the best, but I don't think that's a good use of time.

quick update, this happened because I did not append the hydroedge feature class with the ftype and elev fields that were created when i made the hydroedges (when i ran the drainage connectivity characterization tool, i set the output to temp feature classes and then loaded the data into the hydroedge and hydrojunction GWIS classes). Clicking the blue question mark at the top right corner of the tool helped!
