clone_items throws "IndexError: list index out of range" when there are nested repeats in the featureservice

[nojha-g]

Describe the bug
A clear and concise description of what the bug is.
When I use the code to clone items for feature service and if it has nested repeats I get the error and fails to clone.

To Reproduce
I have a feature service with following
FeatureLayer (id=0)
Table 1(id=1) --> related to layer 0
Table 2(id=2) --> related to Table 1

Steps to reproduce the behavior:

copydata = True
item_id_test ='a8a819c2efab4c8ab3aaed5bfbe74b14'
print(datetime.now().strftime("%Y/%m/%d, %H:%M:%S"))
source = GIS(source_enterprise_url, source_username, source_password,  use_gen_token=True)
target = GIS(target_arcgisonline_url, target_username, target_password,  use_gen_token=True)
#print("s",source)
#print("t",target)
it = source.content.get(item_id_test)
target_user=target_username
foldername='0_Migration_Test_Folder'
cloned_items = target.content.clone_items(items=[it], folder=foldername, owner=target_user, copy_data=copydata,use_org_basemap=True)#,item_mapping=map_service_item_mapping)

error:

Also I would like to mention that if the process takes longer than 60 min, it will fail with invalid token error. I tried several ways to see if the expiry time of token to be longer, but I am not able to do so. When using rest API, I am able to have longer expiring token but not with the Python API using "arcgis.gis".
