I am using ArcGIS Pro.
I am trying to create a model to iterate through three feature classes in a file geodatabase, all with the same schema. The model performs several joins and field calculations before eventually returning a feature class with several more fields in addition to the original fields. My problem is that the original fields aren't showing up in the model. For example, when specifying a join field, I get:
Warning 000728: "Field ___ does not exist within the table"
As a result, they don't show up in the final feature class either.
What am I doing wrong?
Here's a screenshot of the relevant part of the model:
