I am also getting the same error as follows:
File "C:\Program Files (x86)\ArcGIS\Desktop10.2\arcpy\arcpy\arc.py", line 1727, in Dissolve
raise e
arcgisscripting.ExecuteError: ERROR 999999: Error executing function.
Failed to execute (Dissolve).
I am trying to implement some code in python deploying arcpy in Ecllipse.
With the Dissolve function, I want to remove Pseudo nodes of my road network and below is the code:
arcpy.Dissolve_arc(self.address_ref_layer1, self.address_unSplit_ref_layer1, dissolveFields, "LINE")
required info:
Windows7 Enterprise, Sp1, 64-bit
Intel(R) Core(TM) i7-3770 CPU@ 3.4GHz
RAM 8 GB
ArcGIS 10.2.2
Could you please help me how to resolve the problem or give me a workaround for this issue?
