Updating SharePoint List items REST API - Bad parameter passed to Web Server Extensions

Question

I have a Python script (snippet below) that I've been running for months that uses shareplum to update various columns of a SharePoint List. It has suddenly stopped working and I've no idea why. The script runs without any errors but the changes are not made. Creating a new List item is working fine, it's only when I try to update an existing List item. I'm able to update columns of other Lists using the same script so it must be an issue with this particular List. I checked the result of the response, which says: '0x80070057', Bad parameter passed to Web Server Extensions.

I am able to use Office365-REST-Python-Client to update the list items of the List in question but I'd love to know why I'm having this issue with the shareplum script and if there's an issue with my List.

from shareplum import Site  
from shareplum import Office365  
      
  
authcookie = Office365('https://XXX.sharepoint.com', username= XXX, password= XXX).GetCookies()  
site = Site('https://XXX.sharepoint.com/sites/XXX', authcookie=authcookie)  
list_ = site.List('TestList')  
  
my_data = [{'ID': '3', 'Title': 'TestTitle'}]  
list_.UpdateListItems(data=my_data, kind='Update')
