[Help] Error Encountered: An item with the same key has already been added


We are experiencing the same issue - has anyone been able to resolve this issue or otherwise find a workaround?

Hi, I was unable to solve this so used the following workaround: 1. Created new list in SharePoint 2. Used Alteryx to write new to list (list of changed/updates required to main list) 3. Used a SP workflow to make changes to original list using values in new list. All in all, not ideal as I then encountered throttling issues with SP online so needed a batch macro to regulate writing to list.
