I have an app that has been working for over a year. I made changes to the app a day ago and everything was working fine. Today, I was getting errors from users that indicated there was an issue with a data source sharepoint list. The error was seen on launch of the app and said, "The request operation is invalid. Server Response: List Name list faile: Field reference is not supported." I ran the Monitor tool which suggested an error with the operation getLookupResults on app OnStart. I deleted the data source and then readded it. This was successful, however, it is now throwing errors in a power automate flow that uses one of the fields in the sharepoint list. Here is the piece of code that is giving the error:
'REQUESTS|EmailNotes'.Run(TextNotes_5.Text, varUserEmail, varItem.'Created By'.email, varItem.ID, varItem.Title, varUserName)
The 'Created By' column doesn't appear to be recognized. All other columns in the sharepoint list are there. I have refreshed the flow, and tried to add a test label to pull in the varItem.'Created By'.Email and it is not seeing this as a valid column. All other columns in the sharepoint list are available. Any thoughts on what may be causing this error?
