Hey @miranda_luna_db, is there any update or suggestions for the SQL dashboards (so not Lakeview).

I am experiencing exactly same behaviour when attempting to deploy dashboards through the API. I have first fetched an existing definition and I am attempting to create a new dashboard. Creating a dashboard succeeds but the "widgets" property is always null and thus the dashboards end up empty. I feel like my attempt is aligned with the create dashboard API documentation:
"Other fields can be included when duplicating dashboards with this API. Databricks does not recommend designing dashboards exclusively using this API."

The lakeview dashboards are not really an option at the moment for my team as they do not support query parameters.
