I'm struggling with a processing modeler tool. I have a point shapefile (WGS84) which I want to interpolate with the SAGA spline tool. The model is reprojecting the wgs84-points to UTM32N (EPSG:25832). The next step is the spline tool. But I always get this error code:
Error executing algorithm Multilevel b-spline interpolation 'NoneType' object has no attribute 'crs' See log for more details
When I use the points (reprojected manually to UTM32N) with this model (removing reproject layer tool, because the layer is projected to 32N) it works fine.
Is this a bug?
