I have successfully run ArcHydro with previous versions of ArcGIS Pro, but with the latest Pro release I am getting errors with the ArcHydro tools in the toolbox. Specifically, it does not recognize any raster datasets. I'm getting Error 032659, as shown in the screen shot below. I have tried with multiple types of rasters, both in gdbs and outside of gdbs.
I'm wondering if anyone else has come up against this. I was thinking it might have to do with the new version of Pro having a new python library, and that the ArcHydro tools aren't updated to match yet, but I'm not sure on this.
