Unsupported data source warning when dashboard is shared to public

When I shared my Grafana Cloud dashboard to public, I have got “Unsupported data sources” warning.
I use only one postresql data source on all panels. Postgresql is mentioned as supported in grafana documentation.

I am a newbie in Grafana, just wondering if this issue requires any investigation.

The shared link that I have got looks to work fine from the first glans. (Grafana)

Appreciate any advise.

Thank you, maliksohail.

What I am curious about is that after I ignored the warning my dashboard works fine and I do not see any problem.

All panels on the dashboard use only one data source and it is PostgreSQL database hosted on Neon free hosting. PostgreSQL is in the list of supported data sources for public sharing.

Not sure what do you mean about data source should be accessible publicly…
I reviewed datasource definition and did not find any option/parameter to make it public.
