[QGIS-Developer] v.net.centrality: Sorry, <points> is not a valid parameter

Thu Oct 31 01:57:56 PDT 2019

Yes you need to chose an output type yourself, but nomatter what I choose I
get the same error message.

I am running on windows and no matter what Grass procedure I run I get this
warning: 
WARNING: Concurrent mapset locking is not supported on Windows.
Do not know what it means or whether it is relevant in this case?

Error message from v.centrality.net:
