PowerApps automatically renamed the collection fields fro field_

I have an application which was fully working 2 month ago, I had to change all the data source and load new data, on screen visible, I have a clearcollect code that will collect filtered data from a sharepoint list into a collection, usually in this case the collection fields name should be identical to the list field name, but for some reason the collection field names were prefixed by field_ and all field names included in the app was changed as well, any reason why is this happening, and how to fix it?

Can you make sure no user modified underlying SP List field names? Also, pls check the Power App versions to see if anyone made any changes to the app.


If you rule out no changes done by anyone, then we definitely need to check what triggered these changes.


Please confirm.

Hi Krishna,

thank you for your reply, but no at all, I am the only person who can access the app and SP, SP fields are not prefixed with field_

Hello @JohnnyK,


Can you please check the Version of the App weather it changed recently or not.


If not you can raise a Microsoft Ticket to get a better clarity
