I am using the action 'office 365 update items' to try and update the 'name' of my document sets.
I have selected to update all list items:
I have specified the metadata field (name) and the value I want to input (balloon)
The result is that the workflow is suspended and shows the following comment in the history 'unable to find list item to update' (please ignore the 'sharegate' user - it is just the name of my account).
This workflow will complete successfully if I am updating the name of documents.
