In the Modern User Experience (UX / MUX) Idea, Projects, Custom Investments, or Custom Objects modules, when performing a group by in the list view containing an attachment field, the generic error appears:
API-1019 : Could not process the request due to internal error.
The issue occurs when one of the selected columns in the flyout panel is of an attachment field type.
