I am writing a standalone script using QGIS processing plugins. everything works but after adding a new command it gives me some errors. The command is as folloing:
processing.runalg("grass7:v.clean",
BK3,
2,
dgarc,
None,
-1,
0.0001,
BK4,
BKerror)
dgarc is a float number and is equal to 1.BK3 and BK4 are string and are correctly defined. many other processes working with the same strings. The error is as following:
Error: Wrong parameter value: None
