I am trying to create a script tool in ArcGIS Pro that uses 2 clipping feature classes to clip multiple other feature classes and save them to two new geodatabases I create in the script.

I use 6 parameters as GetParameterAsText to specify the conditions:

  • sourceWorkspace (0)
  • ClipFC_North (1)
  • ClipFC_South (2)
  • out_folder_path (3)
  • out_gdb_N (4)
  • out_gdb_S (5)

Below that I try to create the new geodatabases:

arcpy.CreateFileGDB_management(out_folder_path, out_gdb_N)
arcpy.CreateFileGDB_management(out_folder_path, out_gdb_S)

Thats where my script fails and doesn't continue to clip the feature classes in the source geodatabase.

What am I doing wrong? Here is my code up to the point it fails as a script tool.

import arcpy

out_folder_path = arcpy.GetParameterAsText(0)
out_gdb_N = arcpy.GetParameterAsText(1)  # North.gdb
out_gdb_S = arcpy.GetParameterAsText(2)  # South.gdb
sourceWorkspace = arcpy.GetParameterAsText(3)
clipFC_N = arcpy.GetParameterAsText(4)
clipFC_S = arcpy.GetParameterAsText(5)

print(out_folder_path, out_gdb_N, out_gdb_S)

# Execute CreateFileGDBs
arcpy.CreateFileGDB_management(out_folder_path, out_gdb_N)
arcpy.CreateFileGDB_management(out_folder_path, out_gdb_S)

Script Tool Properties

Here is the error message I get:

    out_gdb_* are probably full paths not just filenames, first thing to check is what your parameter values are with arcpy.AddMessage(out_gdb_N) etc...

The problem is with your input parameter TYPES. To understand this you need to read the syntax section of Create File GeoDatabase tool in the help file.

What are the parameter types for the output path and out_name? They are of type Folder and string respectively.

You have set your out_gdb_N and out_gdb_S to both be workspaces not strings.

They need to be simply strings, the name of the geodatabase which will go into your output folder.

Better still don't take my word for it, try using your mouse to scroll the help page down to the code section of ANY tool and you will see some simple sample code using the tool, the rest you can work out.
