Hi,

I start to learn QSWAT in QGIS, To do, so I received a error message creating an HRU.

Steps to Reproduce:
I loaded the learning environment and executed the "CreateHRUs" function.
After running it, I received the error message.
System Details:
Operating System: Windows 10
QGIS Version: 3.33.11 (LTR)
QSWAT+ Version: 1.0.0
Expected Behavior:
The HRUs should be created correctly without causing an error.

This is the Python error message:
2024-10-14T12:33:29 WARNING Traceback (most recent call last):
File "C:\PROGRA1/QGIS331.11/apps/qgis-ltr/./python/plugins\QSWATPlus\QSWATPlus\hrus.py", line 5530, in readFiles

basinData = self.basins[basin]

KeyError: 3

Additional Information:
I also received the following error message: 
ID value 0 from inlets/outlets file D:/xxxxxx/R/Workspace/Flow Direction/Robit/robit/Watershed/Shapes/MainOutlet_snap.shp not found as DSNODEID in channels file D:/XXXXX/R/Workspace/Flow Direction/Robit/robit/Watershed/Shapes/srtm_30mchannel/srtm_30mchannel.shp.

Could it be that these two message are related to each other? How can I solve this error to continue the learning process. I followed and download the fiiles for exercise from here:
