Hi! We’ve just confirmed that this pattern/setup works in Apps, but not in Services. Seems like the fileContent property is not read you read from one datasource to another.

Challenge registered! So for now, you’ll need to select that object from the database connected data source, and update that object instead.

Yup, just a slight clarification, both sources are runtime so it works at initial read to runtime many, but not from many to one.
