The field names are too long for dbf (max 10 characters). The solution would be to allow that "the field may be created in a slightly different form depending on the limitations of the format driver" [0] in v.out.ogr. The ERROR 6 would then change to e.g. > > Warning 6: Normalized/laundered field name: 's_third_quartile' to 's_third_qu'
another solution would be that QGIS uses GeoPackage instead of ESRI Shapefile as vector data exchange format > > Markus M > > [0] https://gdal.org/ogr__api_8h.html#aab585ef1166c61c4819f7fd46ee4a275 >
