I can't seem to get Longest Flow Path for Catchments in ArcHydro to successfully work, as I keep receiving 010429 and 010067 errors when I run it. Does anyone know how to prevent this from happening? I am using ArcGIS 10.6.1 on Windows 10 and the latest version of ArcHydro (10.6.0.13). Although I am new at using ArcHydro, there aren't many inputs for this tool, so I don't understand what I could be doing incorrectly. I've some of the suggestions here, to no avail. Attached is a screenshot of the error message I receive as well as the watersheds and flow lines I was able to delineate for the project I am currently working on.
