Seems like it installed without any problems. Now when i go to my superset dashboard, i find World Bank's Data i click on it, and all the charts say
No results were returned for this query. If you expected results to be returned, ensure any filters are configured properly and the datasource contains data for the selected time range.
Then i check all the example dashboards, all of them have the same written on them. I dont know what could be the issue. Can someone help?
