content.clone_items fails saying item_id exists already while content.get returns none for same item_id

Describe the bug content.clone_items fails for an application saying that the item_id exists currently; however, a content.get call returns nothing for the same item_id.

To Reproduce Steps to reproduce the behavior:

import arcgis
import keyring

dev_admin_user = keyring.get_password("dev-portal", "dev-portal_admin")
dev_admin_pass = keyring.get_password("dev-portal", dev_admin_user)
prod_admin_user = keyring.get_password("prod-portal", "prod-portal_admin")
prod_admin_pass = keyring.get_password("prod-portal", prod_admin_user)

gis_dev = arcgis.gis.GIS(r"https://dev-data.prospertx.gov/portal", dev_admin_user, dev_admin_pass)
gis_prod = arcgis.gis.GIS(r"https://data.prospertx.gov/portal", prod_admin_user, prod_admin_pass)

Screenshots Script Output for Loop User content page in portal/sharing/rest/content/users backend, shows no items that match items asserted to exist.

Expected behavior If an item cannot be returned from content.get() then content.clone_items() should not assert that the item already exists.

Platform (please complete the following information):

OS: Windows 11
Browser: Chrome
Python API Version: 2.1.0.2
Source Portal (10.8.1) Target Portal (10.9.1)

Additional context

When I first tried to copy the content over I had the copy_data = True and received lots of errors. I changed it to copy_data = False and was able to copy over maps but not apps.

Performed a reconfigure and reindex as well to no effect:

indexer = gis_dev.admin.system.indexer
indexer.reconfigure()
indexer.reindex(mode = "FULL_MODE")

Searched for all items using gis_dev.content.search(query="*", max_items=1000) and did not return results with the problem items above.
