Cannot enable anonymous users to view dashboards

I have a dashboard that I want to share publicly. I followed the related steps from the documentation, also linked in https://github.com/apache/incubator-superset/issues/4102: https://superset.incubator.apache.org/security.html#public

Specifically, what I did was:

1. Set PUBLIC_ROLE_LIKE_GAMMA = True in superset_config.py
2. Added datasource access permissions to the Public role, for the datasource from where data in the dashboard is retrieved

Expected results

Anonymous (i.e., not logged in) users shall be able to see the dashboard by opening its URL in a web browser.

Actual results

Anonymous (i.e., not logged in) users are not able to see the dashboard by opening its URL in a web browser: they are redirected to the login page showing an Access Denied error.

I also tried to add some more permissions to the Public user (see screenshots) and managed to display the dashboard, but not the charts in it. However I don’t think it’s the right way to do it, it should work as documented.

Screenshots

Access denied error:

Permissions that I tried to add to Public, together with the datasource access:

What I saw after adding such permissions:

Environment

• superset version: built from master

• I have checked the superset logs for python stacktraces and included it here as text if there are any.

I’m using this config-set for Public access

[can dashboard on Superset, can explorev2 on Superset, can explore json on Superset, can csrf token on Superset, can csv on Superset, menu access on Dashboards, all datasource access on all_datasource_access, all database access on all_database_access, can list on DashboardModelViewAsync, can list on DashboardModelView]

You just need to replace all_database_access and all_datasource_access for the public datasource and database.

I followed the instruction in the link mentioned above (https://superset.apache.org/security.html#public) and now the public role is filled with the same permission as the Gamma one plus all the datasource. But still, the system return “Access is Denied”!
