Issues with Cloning Map Web App from one Organization to another Organization using clone_items() method

Describe the bug Trying to use clone-items() method to clone Map Web App from Organization SOURCE to Organization TARGET in ArcGIS Online. The app is in the SOURCE folder along with 5 other apps. There are 7 Maps and about 60 feature layers in the same folder. The script runs for 10 minutes before backing out. I can see several Feature Layers in the TARGET Folder before the clone method deletes them in the back out process.

To Reproduce Steps to reproduce the behavior:

from arcgis.gis import GIS

# Log into Source ESRI Portal
sourceURL = "https://SOURCE.maps.arcgis.com/home/" # WriteSource ESRI Portal URL here
sourceUsername = "SourceAdmin" # Write admin username here, the script will promp for the password
sourceGis = GIS(sourceURL, sourceUsername)
print("Successfully logged in as: " + sourceGis.properties.user.username)
sourceGis

# Log into Target ESRI Portal
targetURL = "https://TARGET.maps.arcgis.com/home/" # WriteSource ESRI Portal URL here
targetUsername = "TargetAdmin" # Write admin username here, the script will promp for the password
targetGis = GIS(targetURL, targetUsername)
print("Successfully logged in as: " + targetGis.properties.user.username)
targetGis

# Cloning
webMapItem = sourceGis.content.get("c0ac61f6147c4ce2a83610a31ac31cc0")
clonedItems = targetGis.content.clone_items(items= [webMapItem], folder= 'TARGET from SOURCE', search_existing_items=True)

error:

Screenshots If applicable, add screenshots to help explain your problem.

Expected behavior I expect clone_items() to copy the Map Web App, the associated Map, and associated Feature Layers from the SOURCE Organization to the TARGET Organization. I plan to execute the same script for each one of the 6 Apps (they share Feature Layers)

Platform (please complete the following information):

OS: Windows 10 Home
Browser Firefox using Anaconda Navigator / JupyterLab
Python API Version 2.2.0.1 using Python 3.11. (Tried with Python 3.7 and API version 1.8.4 with similar results).

Additional context Add any other context about the problem here, attachments etc.
