Geographic Information Systems Asked by MJM on July 9, 2021
I get the following error in my graphical modeler run log when trying to convert a point shapefile to a raster after running v.distance:

Vector map <vector_60a2a4d19760b74> not found
This operation is being performed in the graphical modeler, and it doesn’t have a problem with this extent layer anywhere else and the results are a-ok.
I have added a define projection and reproject layer operations to the extent layer operation, but the same error comes up.
