Attribute Rules and not loading layers

Ona_Tim — Thu, 11 Sep 2025 21:37:35 GMT

I have created a Field map app to help in road ratings. I created a project in pro with 2 layers and exported to portal. On the WISLR Streets I have an attribute rule to update the paser date when the Road rating is updated

When I open it in field maps the layers fail to load.

The error is as follows:

Domain: com.esri.arcgis.runtime.error

Code: 7018

Description: Arcade expression is invalid.

I have included a screenshot of the attribute rule.

This app will work in portal with no issues.

Thank you for any help

@Ona_Tim - Use a calculated expression in the FieldMaps Designer to calculate the now() in the attribute. Remove the attribute rules.
The calculated fields are a more robust method of calculating fields within fieldmaps.

Here is an update.

Since the Field maps update to 25.2 this has now been working.
