Issues with watershed function in whitebox tools - not generating output

[nicholasmetherall]

Seeking advice with the whitebox tools watersheds function:

I have been using the whitebox tools gui with a DEM to make the d8 pointer flow direction and then with snapped pourpoint, I have been trying to input these to delineate watersheds using the watershed function. However, even though the function loads, no results are generated.

Inputs:

1. d8 pointer flow direction .tif https://github.com/nicholasmetherall/hydrology/blob/main/wbt/dawasamu/4-d8-flow-direction.tif
2. snapped pourpoint.shp https://github.com/nicholasmetherall/hydrology/blob/main/wbt/dawasamu/pourpoints/snapped-pourpoints.shp

Outputs
Not working / maybe there is a bug

The python code and steps are here: https://github.com/nicholasmetherall/hydrology/blob/main/wbt/2-delineate-catchments.ipynb

Any help or advice on how to debug this issue / lack of outputs from the watersheds function would be much appreciated.

I have also tried to work outside the gui by just using the python commands to access the wbt functions but this is also leading to bugs / issues :

This script can be used to replicate the bugs and issues with wbt -for the example of the wang and liu fill depressions function : https://github.com/nicholasmetherall/hydrology/blob/main/wbt/dawasamu/3-combined-workflow.ipynb
