I am in the process of copying dashboards from ArcGIS Online to ArcGIS Portal but running into issues. My current workflow is to create a blank dashboard in Portal and copy the JSON from the Online dashboard to the Portal dashboard using ArcGIS Online Assistant, changing the version and updating any layer references.
There are no errors displayed but when opening the Portal dashboard, it doesn't show any data. Am I missing anything in the JSON that needs to change/get updated? Or is it not possible to transfer Dashboards from AGOL to Portal.
Any help would be appreciated, thanks!
