Using SkyViewFactor in ArcGIS-Modelbuilder fails on r=kwargs['raster_info']

[ThatMikaTho]

I am trying to use the SkyView-Function inside my ArcGIS Pro model. I tested the function manually with the raster function and the same raster and it works, but using "Generate Raster From Raster Function" returns ERROR 99999 saying the following:

ERROR 999999: Something unexpected caused the tool to fail. Contact Esri Technical Support (http://esriurl.com/support) to Report a Bug, and refer to the error help for potential solutions or workarounds.
