ArcGIS Pro 2.9 Create Domain, Assign Split and Merge policies not working in Python

Question

Since upgrading to ArcGIS Pro 2.9.3, and possibly 2.9, I am unable to assign the split and merge policies in Python when using the Create Domain (Data Management) tool. I have a large script which calls this tool multiple times to set up various domains.

Code sample 1 runs: arcpy.CreateDomain_management(fileGDB, "PointTypes", "Various symbology types for points.", "TEXT", "CODED")

Code sample 2 does not run: arcpy.CreateDomain_management(fileGDB, "PointTypes", "Various symbology types for points.", "TEXT", "CODED", "DUPLICATE", "AREA_WEIGHTED")

Error message: arcgisscripting.ExecuteError: Failed to execute. Parameters are not valid.
ERROR 000800: The value is not a member of Use the attribute's default value.

Duplicate and Area Weighted are both valid parameters according to the tool reference page. Any help trouble shooting this will be helpful.

Hi,

in code sample 2, you can't have "Area_WEIGHTED" on the Coded domain. it's only applied to the range domain.

check the reference page ... "The area weighted policy only applies to range domains."

Cheers,
