clone_items 'NoneType' ojbect has no attribute 'metadata'

ResourceAnalyst

Hi,

I'm attempting to build a simple script to migrate an Experience Builder app from a development to production environment but receiving 'NoneType' ojbect has no attribute 'metadata' on the final line.

The item_to_migrate is an object and does have a valid metadata property unless that's not the problem here?

from arcgis.gis import GIS

portal_password = '***'
user = '***'

dev_gis = GIS("https://***/portal", user, portal_password)
prod_gis = GIS("https://***/portal", user, portal_password)

item_to_migrate = dev_gis.content.get("1ff4d32bc2344739b6b4e4df61f5de08")

clone_result = prod_gis.content.clone_items(items=[item_to_migrate],folder="Asset")

I am getting a similar issue after I clone an item, I use:

item_dst.move(folder_name)

and I get the following error:

Traceback (most recent call last):
File "<string>", line 1024, in <module>
File "C:\GISData\ArcGISPro_PythonClone\envs\arcgispro-py3-clone\Lib\site-packages\arcgis\gis\__init__.py", line 17232, in move
folder_id = self._gis.content.folders.get(folder=folder)._fid
AttributeError: 'NoneType' object has no attribute '_fid'

I have talked to ESRI support and their are known bugs for cloning all apps with the clone.items() function. I have been told there is no current work around or other functions that could be used on cloning Apps and these bugs will be addressed in the ArcGIS API Python 2.4 release. Which they do not have an official release date for but possibly October 2024.

To me this makes all the documentation out there on cloning items irrelevant.

I am experiencing the same issue with clone_items() on Portal 11.1.

Did you ever find a solution? Thanks in advance for any suggestions!

ResourceAnalyst

Thanks again,

Portal 11.1

Exception has occurred: AttributeError

Hi @ResourceAnalyst, What version of portal do you have deployed? and can you add the track trace e.g. the error that you get from the script?

Other methods you can try to use is collaboration or try using the group migration manger
arcgis.gis module | ArcGIS API for Python
is creates a package that you can import on the other system.

ResourceAnalyst

Thanks,

The source data is already published and I have added those 2 flags but the same error above remains. Object from VS Code as below:

Hi @ResourceAnalyst, are you sure that you are getting an object back on your item_to_migrate?

Things to look out for:

if your source data is not a hosted feature layer you have to first manually publish it in the destination
I would turn on preserve item id flag if it is enterprise.
also try to set the copy_data flag to false.

Hope it helps

Henry
