I created a field maps app several months ago that includes an arcade expression to calculate the DueDate field for features that are added to the app. I used the FeatureSetByName function to access attributes in a static road feature service (i.e. a copy of our roads feature layer). Recently, someone in my organization added a new roads feature service that reflects our 'live' data i.e. it updates as the feature is edited in our SDE geodatabase. This layer was added to portal and the portal item was added to ArcGIS Online with stored credentials. When I try to reference the new layer in my expression I receive the following error: Test execution error: Unknown Error. Verify test data. Does anyone know why I cannot use the same expression to access attributes in the 'live' roads feature service?
