Unable to Overwrite Existing Cached Map Service Using MapImageSharingDraft

Hi, I'm trying to publish a map service using Python and ArcPy.
Even though I set sddraft.overwriteExistingService = True, the service is always published with a timestamp appended (e.g., Tainan_ZonePrice_202505151610) instead of overwriting the existing service.

I have already registered the target folder on the GIS Server, and the service name I'm using matches the one that already exists in that folder.

Here is a simplified version of my code:

import arcpy import os import xml.dom.minidom as DOM from dataclasses import dataclass import requests import xml.etree.ElementTree as ET import xml.dom.minidom as minidom # Modify portal URL, username, and password portal_url = "https://test/portal" server_username="" server_password="" arcpy.SignInToPortal(portal_url , server_username, server_password) print("Signing in to portal...") @dataclass class Service: aprx_name: str # Project file name aprx_path: str # Path to the .aprx file serverFolder: str # Folder on the server to publish to map: str # Map name (only needed if named) service_name: str # Name of the service mapOperations: str # Operations (Map, Data, Query) maxRecordCount: str # Max record count (default is 2000) groups: str # Shared groups, separated by commas (e.g., "Group A,Group B") sharingLevel: str # Sharing level: OWNER, ORGANIZATION, or EVERYONE MapImage = { 1: Service("Tainan_ZonePrice", r"D:\MapData\Tainan_ZonePrice\Tainan_ZonePrice.aprx", "publish_test", "map", "Tainan_ZonePrice", "Map,Data,Query", 2000, "", "EVERYONE") } print(MapImage[1].aprx_name) for key in [1]: try: # Output folders outdir_1 = r"D:\MapData\sddraft" outdir_2 = r"D:\MapData\sd" # Generate filenames for draft and service definition aprx_name = MapImage[key].aprx_name sddraft_filename = aprx_name + ".sddraft" sddraft_output_filename = os.path.join(outdir_1, sddraft_filename) sd_filename = aprx_name + ".sd" sd_output_filename = os.path.join(outdir_2, sd_filename) aprx_path = MapImage[key].aprx_path aprx = arcpy.mp.ArcGISProject(aprx_path) print(aprx.listMaps()) m = aprx.listMaps(MapImage[key].map)[0] print(m) service_name = MapImage[key].service_name print(service_name) # Replace with your federated server URL federated_server_url = "https://test/server" server_type = "FEDERATED_SERVER" sddraft = m.getWebLayerSharingDraft(server_type, "MAP_IMAGE", service_name) sddraft.federatedServerUrl = federated_server_url sddraft.enableCache = True sddraft.cache.configuration = r"D:\MapData\ArcGIS_Online_Bing_Maps_Google_Maps.xml" # Tiling scheme sddraft.overwriteExistingService = True sddraft.copyDataToServer = False sddraft.portalFolder = MapImage[key].serverFolder sddraft.serverFolder = MapImage[key].serverFolder sddraft.maxRecordCount = MapImage[key].maxRecordCount sddraft.mapOperations = MapImage[key].mapOperations sddraft.sharing.sharingLevel = MapImage[key].sharingLevel sddraft.sharing.groups = MapImage[key].sharingLevel sddraft.exportToSDDraft(sddraft_output_filename) if os.path.exists(sd_output_filename): os.remove(sd_output_filename) print("Start staging") arcpy.server.StageService(sddraft_output_filename, sd_output_filename) warnings = arcpy.GetMessage(1) print(warnings) print("Publishing service...") print("Start uploading") federated_server_url1 = "https://test/server/rest/services/publish_test" results = arcpy.server.UploadServiceDefinition(sd_output_filename, federated_server_url1) print("Upload complete") print("Start managing cache tiles") service_url = f"https://test/server/rest/services/publish_test/{service_name}/MapServer" scales = "295828763.795777;147914381.897889;73957190.948944;36978595.474472;18489297.737236;9244648.868618;4622324.434309;2311162.217155;1155581.108577;577790.554289;288895.277144;144447.638572;72223.819286;36111.909643;18055.954822;9027.977411;4513.988705;2256.994353;1128.497176" arcpy.server.ManageMapServerCacheTiles(service_url, scales, "RECREATE_ALL_TILES") print("Cache management complete") except arcpy.ExecuteError: msgs = arcpy.GetMessages(2) print(f"Arcpy execution error: {msgs}") except Exception as e: print(f"Other error occurred: {e}")

No matter what I try, ArcGIS Server always appends a timestamp to the service name instead of overwriting the existing one.
I have confirmed that:

The service name matches an existing service.
The folder is correctly registered.
The overwriteExistingService flag is set to True.
Is there anything I am missing to ensure the existing service is truly overwritten, instead of creating a new one with a timestamp suffix?
Thanks in advance!
