Research direction

Start with the Python SDK path used by await ...items.get(...) and trace how the SharePoint list field value is deserialized. Reproduce the case with a text field containing "PT" and add a focused regression test; done means the value remains the string "PT" rather than becoming datetime.timedelta(0).

Description

Needs: Attention :wave: type:bug
Describe the bug

I am trying to iterate through a SharePoint list entries/rows for further processing:
...
list = await client.sites.by_site_id(site_id).lists.by_list_id(list_id).items.get(request_configuration=request_config)

rows = []
for item_id in list.value:
fields = item_id['fields']
rows.append(fields.additional_data.get("code")) # test
rows

but when text/string field have value 'PT' it is retrieved as a datetime (exactly: "datetime.timedelta(0)"). It makes my code useless for keeping for example 'Country Code' as list's field. I have seen similar issue before with 4-digit strings, so maybe it is related.

Please, take a moment to look at this.

here some screenshots:

list in SP (just field 'code' and its values) :

and my code results:

Expected behavior

Expected behavior would be to display 'code' the same way as it is in SharePoint list, means:
PT
PTA
..

How to reproduce

To reproduce please just create new list with text field. Then add value 'PT' to this field and try to use await client.sites.by_site_id(site_id).lists.by_list_id(list_id).items.get(request_configuration=request_config) for entried reading.
