Scripts - Background cannot update read-only fields after upgrade

[Community Alums]

We recently upgraded from London to New York.  

After the upgrade, some of our scripts we use in scripts - background can no longer update records, giving the following error: 

Background message, type:error, message: Data Policy Exception: 
	The following fields are read only: field1, field2

Is this something simple like an ACL, or was there a change to the way those scripts are run?

So they would have fixed some bug as part of New york release. So you need to deactivate the data policy
