TOPO correction returns noise

[jantin1]

I am trying to correct an aerial hyperspectral image topographically. I have a DEM acquired in the same time as the image and with the same spatial resolution and coverage. I have created slope and aspect maps and calculated solar angles and fed the whole package to hyTools. I used modified scripts from this github to create a config .json and to perform the correction. Nevertheless the result of the processing is colorful noise, which looks like it has nothing to do with the HS image or the DEM. What do I do wrong to get this kind of result? Is there some setting or input I forget or don't know about? Attached is the image of my product. I work on PopOS flavour of Ubuntu.
