I am using QGIS version 2.18.9. I first create a graphical modeler and it is working. Then I export it to python script. While I am running the script I got following error massage.

"NoneType' object has no attribute 'getitem See log for more detail".

Can you explain the reason?

My script is shown below:

##Testing=name
##drawingdxf=file
##cleanf=output vector
outputs_GRASS7V_IN_DXF_1=processing.runalg('grass7:v.in.dxf',drawingdxf,'1',True,False,True,False,False,True,['200000.000000,700000.000000,200000.000000,700000.000000'],0,None)
outputs_GRASS7V_CLEAN_1=processing.runalg('grass7:v.clean', outputs_GRASS7V_IN_DXF_1['output'],1,0.1,['200000.000000,700000.000000,200000.000000,700000.000000'],-1.0,0.0001,cleanf,None)

You are getting the error because of points in variable name. Variable name doesn't include points. Try to change outputs_GRASS7V.IN.DXF_1 into outputs_GRASS7V_IN_DXF_1 or something else without points.
