Python script unable to find target server

RVx_GaslineGiS — Mon, 03 Jul 2023 14:53:04 GMT

I'm trying to overwrite a published service on a federated server. I've been following the ESRI sample script here: https://github.com/jnshill/ArcPyPublishing/blob/8af7523a692498e4c22a142dfc940e3c355efaba/PublishLayersAsMIL_FA_Timezone.py#L95 without much success.

Despite assigning the federatedServerURL, I get a "Missing target server" error. I've confirmed that the token I pull from the Portal works by singing into the REST API. I verified the federated server URL by logging into the Portal Administrator Directory -> Federation -> Servers and snagging the URL field from there.

However, even with all of that....still missing target server. In the python code, I can call the .federatedServerURL and it will yield a result that matches with what is in my administrator directory.

Anyone have any ideas on what else to check?

outdir = r'D:\\location' ## Folder the Map Service will Go too in_folder="Folder1" service = "servicename" sddraft_filename = service + ".sddraft" sddraft_output_filename = os.path.join(outdir, sddraft_filename) # Reference map to publish aprx = arcpy.mp.ArcGISProject(r"C:\\Project.aprx") # Get first map m = aprx.listMaps("MapName")[0] # List enterprise URl and credentials here portalURL = r"https://portalServer/webAdaptor" fed_server = r"https://ServerURL/webAdaptor" cred_detail = [] #sign into credentials portal_pw = keyring.get_password("stuff", "user") portal_user = "user" #Sign into Portal arcpy.SignInToPortal(portalURL, portal_user, portal_pw) # Create MapImageSharingDraft and set service properties sharing_draft = m.getWebLayerSharingDraft("FEDERATED_SERVER", "MAP_IMAGE", service) sharing_draft.federatedServerURL = fed_server sharing_draft.portalFolder = 'Folder1' sharing_draft.description = "Description" sharing_draft.credits = "Name" sharing_draft.tags = "Tags" sharing_draft.copyDataToServer = False sharing_draft.overwriteExistingService = True sharing_draft.exportToSDDraft(sddraft_output_filename)

That url advice in the documentation is maybe right for some, but for us we had to use the https://domain/arcgis url. using /webadapter as suggested fails.

However, my script gets up to the stage service and the bombs with 999999.

Hi @RVx_GaslineGiS ,

Were you able to resolve this issue?

I was getting the error "Missing target server" and found out the cause was this property:

# correct sharing_draft.federatedServerUrl

In the code snippet from @RVx_GaslineGiS the '...Url' part is written as '...URL', in uppercase instead of capitalized:

# wrong sharing_draft.federatedServerURL

Using ArcGIS Pro 3.3.4
