Error Creating HAND based on Distance with Catchment Raster

SarahMikkelsenMDEM — Mon, 09 Jun 2025 17:20:13 GMT

I'm following the tutorial "Creating Flood Depth Rasters for Flood Impact Analysis" from June 2023 with ArcHydro, and twice I have made it all the way through the tutorial and get stuck on the Creating HAND based on Distance with Catchment Raster step. Here is the text of the error message that I am getting. Looks like its having an issue with "Nibble", any suggestions?
I would use the "Create Hand Based on Flow Direction" tool, but I don't know what to use for the "minimum raster"
