How to connect to Cloud SQL Postgres table from Cloud Run

[adam-heat1]

I can't get past my Configuration(EmptyHost) error when hitting my database from Google Cloud Run.

I am able to run locally just fine connecting to my table by passing

let connection_string = postgres://user:password@ip:port/db_name

let pool = PgPoolOptions::new()
            .max_connections(5)
            .connect(connection_string)
            .await
            .expect("Failed to connect to Postgres");

This doesn't work when I deploy to Google Cloud Run though. I tried changing the ip section to my unix socket /cloudsql/project-id:region:cloud-sql-name but that didn't work either.

I also moved to use connection_options like this

 let connect_options = PgConnectOptions::new()
            .host("/cloudsql/project-id:region:cloud-sql-name")
            .username("user")
            .password("password")
            .database("database");

let pool = PgPoolOptions::new()
            .max_connections(5)
            .connect_with(connect_options)
            .await
            .expect("Failed to connect to Postgres");

All of these give me an error of Configuration(EmptyHost). How can I get more details to get past this issues?

Thanks in advance for the help
