I'm trying to split several lines into bits of a maximum given length using v.split. First, I got this bug:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe8 in position...
which was solved downloading the new QGIS version 3.4.2 But now, using QGIS 3.4.2 under WIN8-64 bits, I get several warnings and this new errors:
Starting GRASS GIS...
WARNING: Concurrent mapset locking is not supported on Windows.

WARNING: Unable to open database ... by driver
ERROR: Unable to open database ... by driver
WARNING: Unable to open vector map on level 2. Try to rebuild vector topology with v.build.
ERROR: Unable to open vector map
ERROR: Vector map not found
I tried to save the output as a shp file instead of a .gpkg but it doesn't work either.
