I'm trying to start my server but I'm getting an error "throw new Error('SASL: SCRAM-SERVER-FIRST-MESSAGE: client password must be a string')

Question

This line of code is the issue , once i remove it, i can start the server right away

const { Client } = require("pg");

let DB_URI;

if (process.env.NODE_ENV === "test") {
  DB_URI = "postgresql:///users_test";
} else {
  DB_URI = "postgresql:///users";
}

let db = new Client({
  connectionString: DB_URI
});

db.connect();

module.exports = db;
