How to connect amazon aurora rds postgresql with Parse server running in a EKS cluster?

Question

I have been trying to get parse server up on my EKS cluster. but the pods fail giving the error no database "dbname" does not exist. I have another app deployed on the server (nakama game server) that is connected to an RDS postgreSQL. the security group used for both RDS are exactly the same. so i am failing to understand why parse server is unable to find the database.

here is the error thrown by the pod--->

error: database "database-2" does not exist

}

here is the config.js -->

const ParseServer = require("parse-server").ParseServer;
    const databaseUri =
      "postgresql://username:password@database-2.cluster-cum5cpuwordc.ap-south-1.rds.amazonaws.com:5432/database-2";
    const parseServerConfig = {
      appId: "assessment-service",
      masterKey: "masterKey",
      clientKey: "client-key",
      appName: "relive",
      cloud: "./cloud/main",
      // serverURL: "http://<your-parse-server-url>/parse",
      databaseURI: databaseUri,
    };

please let me know if you need any more information.

rechecking the database uri
