Problems with create HRUS

[Xiao Zhang]

Hi, I have met with this problem when I tried to create HRUs by "Fliter by landuse, soil, slope". Does anyone know how to handle this?

I have never seen this error before, and the message about an 'unknown'
exception is not very helpful! If you send me a zip of your project
directory I will investigate.

OK. But the project is a bit large, like 12G unzipped. How can I send this file to you?

[Xiao Zhang]

I tried with the new QSWATPlus  version  2.1.0, the HRU was created successfully with "Fliter by landuse, soil, slope". The version I got this problem is 2.0.6. Maybe the new version have fixed this problem. Though I don't know why, the result is good. Hope it won't happen again.

Hi Chris,

I met this problem again with version 2.1.0. I totally confused. How can I send my project to you?

Hello

Tell me please if ypu have found the solution for this problem, I'm getting this error message using QSWAT+ 2.2.4 and 2.2.3 when using multiple HRUs option.

I too am having the same issue when trying to create HRUs. This is with "Filter by landuse, soil, slope" (both by area and percentage), the other methods work as expected.

This is with:

QGIS 3.22.11

QT Version 5.12.8

GDAL/OGR Version 3.0.4
