Dear @Vernard,

Welcome to the Community!

This happens when your AWS CLI configuration does **not have a region set** , or the region is incorrect.  
The endpoint in the error message shows: `https://rds..amazonaws.com`

Notice the double dots `rds..amazonaws.com` — the region part is missing between them.

Thanks for the clarity, how do i then include which region since the command given is ``  
aws rds describe-db-instances --db-instance-identifier --output text --query “DBInstances.Endpoint.Address”``
