[Dashboard Export] Export fails when a widget contains a dynamic "in regard of" filter

[Lhorus6]

Description

Dashboard and widget exports fail silently when a widget contains a in regard of (dynamic) filter. Clicking the export button produces no output, no file is downloaded, no error is displayed, and no feedback is given to the user.

The issue affects both the full dashboard export and the individual widget export.

Removing the in regard of (dynamic) filter from the widget restores normal export behaviour.

Environment

OCTI 6.9.18

Reproducible Steps

Steps to create the smallest reproducible scenario:

1. Navigate to Dashboards and create a new dashboard.
2. Add a new widget with the following configuration:
   • Visualization: List
   • Perspective: Entities
3. In the widget filter panel, add a dynamic filter:
   • Filter key: In regard of (dynamic)
   • Relation: contains
   • Sub-filter: Entity type = Report
4. Save/validate the widget.
5. Attempt to export the widget (e.g. via the widget action menu).
6. Alternatively, attempt to export the entire dashboard.

Expected Output

The export is generated and downloaded (JSON file for dashboard/widget export) as usual.

Actual Output

Nothing happens. No file is downloaded, no error message or notification is displayed. The export action is completely silent.

Additional information

• The issue is specifically tied to the in regard of (dynamic) filter. Widgets without this filter type export correctly.
• Both dashboard-level and widget-level exports are affected.
• No error is visible in the UI.
