Publishing certain data with feature access enabled to ArcGIS Server causes the Query widget to fail when added to Portal for ArcGIS as an item and then configured in Web AppBuilder for ArcGIS.

解决办法

1. Delete one of the relationship classes and republish the feature service.
2. Delete fields in the feature classes until there are fewer than 100 fields, then republish the feature service.
3. Remove the Arcade expression.
