I couldn't get the fetch or look up an item to work for me after I uploaded a file (just as your workflow shows here), and at the same time I was also using the ms graph api to verify/validate the name or id of the file.
I ended up using the Search for an Item option using the Search.FileLeafRef == Upload.Name, and I set the limit to 1. I also ran into an issue with trying to use the Date as an additional qualifier, so I resorted to just the Date value for Created at.
Within your update item step, you should now see the fields to update option.
Thanks....I'll give that a try.
