I have a cloud based Postgres DB that I want to connect to Google Data Studio, both are part of the same GC project. When I try to use the built in connector for postgres through Data Studio I receive error Error ID: ff6a9ba9. I know my DB is working because I can connect to it outside of Data Studio

I tried using the same Postgres public IP that I can connect to from my local machine but I had to whitelist that. The problem with connecting Data Studio is I don't know the IP address of that server, so I can't whitelist it. Is there a different type of connection to use within the same GCP Project (sort of how App Engine also requires the "Connection Name")?
