Published Dashboard without charts can only be reached by owners about superset HOT 1 OPEN

The issue you're encountering with dashboards without charts not being accessible to users with the gamma role seems to stem from how Superset manages dashboard visibility and access permissions. In Superset, access to dashboards is controlled by user roles, permissions, and checks for administrative status or ownership. Specifically, the gamma role is designed to limit access to only those data sources and the associated dashboards and charts that the user has been explicitly given access to. Since dashboards without charts do not have any associated data sources, they might not be visible to gamma users based on the current permission setup.

The 404 Not Found error you're seeing when a gamma user attempts to access a dashboard without charts is likely due to the system's inability to find a valid permission set that allows access to the dashboard. The workaround you've discovered, adding an empty chart to make the dashboard accessible, aligns with this understanding, as it introduces a data source to the dashboard, potentially making it visible to gamma users based on their permissions for that data source.

To address this issue, it might be necessary to explore modifications to the Superset codebase or configuration to allow gamma users access to dashboards without associated data sources. This approach, however, would require a deeper dive into the specifics of Superset's permission handling mechanisms and might not be straightforward depending on your setup and requirements.

This explanation is based on the current understanding of Superset's security model and the behavior you've described. If you have further questions or need more detailed assistance, please feel free to ask.
