Thanks, James. Adding the position parameter does seem to work. Does anyone know of a way to add an item to the end of the children list without having to count the number of existing children? Using -1 (negative one) does not work as “Offsets must be greater than or equal to 0”.

I’m trying to use the Set the parent/position of an Archival Object in a tree<https://archivesspace.github.io/archivesspace/api/#set-the-parent-position-of-an-archival-object-in-a-tree> API endpoint but I am getting an error when I supply both the archival object ID and the parent ID in what should be the correct way. The Archival Object is an item-level record and the parent is a series-level record, both under the same Resource. The error is: { "error": "comparison of Integer with nil failed" } Here is some sample Python code that fails: ``` import json from asnake.client import ASnakeClient asnake_client = ASnakeClient() asnake_client.authorize() parent_post_response = asnake_client.post( "/repositories/2/archival_objects/96413/parent?parent=96414" ) print(json.dumps(parent_post_response.json(), sort_keys=True, indent=4)) ``` The locally installed ArchivesSpace version that I am testing on is 2.8.1 currently. Thanks for any help. Cheers, Tommy
