Error: Error: getaddrinfo ENOTFOUND ""

For my react-Node app, I have hosted the frontend and backend code on render and I am using a third-party website ( for hosting my database. I have successfully deployed both my front and backend on, but once the site goes live, i get this error from the backend code.

Upon some research, i found that this could be an issue related to not correctly setting up a database connection, so Itried doing, it, checked my db credentials but the error’s still there.

This is how I am setting up my database:

const pool = createPool(
        host: process.env.MYSQL_HOST,
        user: process.env.MYSQL_USER,
        password: process.env.MYSQL_PASSWORD,
        database: process.env.MYSQL_DATABASE

and this is the .env file for the ENV variables:


Any help would be great,
