Hello there,
I have built the visitor request automation app. There is a request submit form/screen and approval screen. In terms of process, everything is going well. When the approval is completed, it successfully moved to the next screen (screen shot below), updates the status in the sharepoint list, send automated email etc. But I still get this error on the top of the screen. I checked every single field including hidden fields - everything has data in it. Except the Title field, none of the fields are "Required" in the SharePoint list.
Since there are so many other processes and set up which are built around this app, I do not want to risk removing the data base and reconnecting it. Is there any other way to fix this error?

Approval form:
