Error: Output path does not exist: #
When converting feature classes to geodatabase, and the path to the source data is over 2000 characters, an error will occur:
"Running script FeatureClassToGeodatabase...
Output path does not exist: #
Completed script FeatureClassToGeodatabase...
Failed to execute (FeatureClassToGeodatabase_6)."
Critical length of the multivalue is near 2000 characters. The sys.argv line in featureClassConversion.py is not sufficient for strings of this length.
Solution or Workaround
Store the data in a path that is less than 2000 characters.
