I am moving a simple ModelBuilder model from ArcMap(where it works fine) to ArcGIS Pro. It is to iterate through a selection of fields and then make a feature layer to use to select against. I keep getting the error it cannot open the out put of the Iterate Row (see error below). I have also tried Iterate Row Selection with the same error.

I switched out the Iterate Row to Iterate Feature Selection and that seems to have done the trick. I am still not sure why this would not work in Pro as it did in ArcMap but at least I can move forward now.
