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.

Version affected:
CDV 7.1.9 and 7.2.0
