Error when cloning Survey123 form

[HanliePetoors]

Hi,

I'm using the process outlined here to try and clone a survey from AGOL to an enterprise portal.

Everything works fine up until the line where I actually clone the items:

# Identify the folder associated with the survey
fldr = next((f for f in full_folder if f['id'] == survey_folder), 0)
#List all the items within that folder to be cloned later on
fldr_items = usr.items(folder=fldr)
# Create a new folder with the same name as the source folder to clone the contents to
target.content.create_folder(folder=fldr['title'])
# Clone items to the new folder
cloned_items = target.content.clone_items(items=fldr_items, folder=fldr['title'])

This gives me an error 

_ItemCreateException: ('Failed to create Feature Service EIIF Monitoring Tool V6: {\'code\': 500, \'message\': "The submitted field \'creationdate\' is not available in the layer \'0\' of the service \'Hosted/service_3053a\'.", \'details\': []}', <Item title:"service_3053a" type:Feature Layer Collection owner:myusername>)

The source survey has a field called 'CreationDate' that Survey123 added itself. I don't know why the clone method is looking for a field called 'creationdate'.

Does someone know how to resolve this error?

Thanks

Hanlie
