Script fails to create Vector Tile Package based on Portal environment

[Brian_McLeer]

I am working on a script that will create a Vector Tile Package from ArcGIS Pro and publish to Portal. In my testing portal environment, it functions as expected. When I switch the Portal URL, ItemIDs, etc to my production Portal, I get the below error. 

ERROR - Error updating item PortalItemID: ('Failed to create Vector Tile Package MapName: Item with this filename already exists. [itemId=PortalItemID]\n(Error Code: 409)', None)

Does anyone have any suggestions on what might cause this behavior to exist in one instance of Portal but not another? The environment is ArcGIS Enterprise 11.2.

Does arcpy.Exists return true when you run out on the output item path? It seems like you either already have an item with that name on your production server or you are creating it twice in your script. Given that your development server test worked I think it's probably the former.

You could test this by running an Exists check and just appending a '_new' to the file name. That way it will say least complete and show you something.

Maybe some debugging and handle the 409 error when publishing a Vector Tile Package

untested.
