"Cannot use Assigned Data source" error

Hi All,

My Dashboard application is built with Universe as source. After days of development an error suddenly appeared "Cannot use Assigned Datasource".

I checked blogs and implemented the code
to assign data sources explicitly to all components. (setDataSourceAlias)... this workaround is working fine except for the Geo Map because in Geo Map we do not have any method to assign data source explicitly.

This is an inconsistent error because it disappeared for a day and then reappeared with no changes in code.

Please advice.

Thanks & Regards
