- Dashboard export from Visuals page results in corrupted JSON
-
Exporting a dashboard from the Visuals page results in corrupted JSON, impacting the successful export and import of dashboards from the page. The issue manifests during the export process, resulting in a JSON structure that only contains workspace details.
- Workaround:
-
To resolve this issue, consider the following workarounds:
-
- Single report export
-
For exporting a single report, use the export action within the Dashboard Builder. This method avoids the JSON corruption encountered on the Visuals page.
-
- Multiple reports export
-
For exporting multiple reports, access the Visuals page with the query parameter
?mode=old
. This opens the old Visuals page, where the export functionality works correctly, ensuring the integrity of the JSON structure.
