Error in HRU Definition – Soil Raster (ArcSWAT) – Object Reference Error 91

[qaisdar...@gmail.com]

Hello everyone,

I am facing an error while adding the soil raster in the HRU definition step in SWAT (ArcSWAT).

The error message is:

Unexpected Program Error
An error has occurred in the application.
Error Call Stack Sequence: CreateOutputFilesDbase LUGridShp.vb Line: 3517
Error Number: 91
Description: Object reference not set to an instance of an object

I have already checked the landuse layer, and it is correctly matched with the raster cell size.

Has anyone faced this issue before? I would really appreciate any suggestions or solutions.

Thank you in advance.
