SharePoint 'Update item' action removing previously patched data from Power App



I am using a Power App that patches form data in the app to Power Automate and following the 'Create item' action in my flow, an 'Update item' action runs where a custom reference number field is prefixed with "UOF-" and suffixed with the list item ID number - so.. "UOF-ID".


Unfortunately I am experiencing an issue during the 'Update item' step where the data from the 'Create item' action is removed - this may be becuase the columns are left blank in the 'Update item' action? Do I need to fill those out again?


*It's worth nothing, this is only affecting Plain text and Yes/No column data!

Hi @sudosaurus 


This may be due to some unpredictable bugs.
I provide a workaround for your reference.
1. Add dynamic content to the empty field in Update item and save the flow.
2. Delete these dynamic content and save the flow again.
These two links relate to the same problem as yours which I think might help you:
