Sequelize Connection Issue: SSL certificate not valid

Question

Sequelize Connection Issue: SSL certificate not valid

I am currently in the process of establishing a connection to a PostgreSQL Database that I have configured on Heroku.

const { Sequelize, DataTypes, Model } = require("sequelize");

// Setting up the database configuration
const sequelize = new Sequelize({
  database: "[won't display db]",
  username: "[won't display username]",
  password: "[won't show password]",
  host: "ec2-54-221-195-148.compute-1.amazonaws.com",
  port: 5432,
  dialect: "postgres",
  dialectOptions: {
    ssl: true,
  },
});

However, the output I am encountering is as follows:

SequelizeConnectionError: self signed certificate

Answer №1

The reason for this issue stems from an unexpected change in node-postgres version 8, which has been documented in detail on this GitHub thread.

To resolve this issue, it is recommended to include rejectUnauthorized: false in the sequelize connection parameters under dialectOptions>ssl, as explained by GitHub user jsanta in their comment available at this link. This effectively bypasses the SSL certificate verification process, a suitable step when connecting to a trusted server via a secure connection like local host or within your own network:

const sequelize = new Sequelize({
  database: "xxxxx",
  username: "xxxxx",
  password: "xxxxx",
  host: "xxxxx",
  port: 5432,
  dialect: "postgres",
  dialectOptions: {
    ssl: {
      require: true,
      rejectUnauthorized: false // <<<<<<< YOU NEED THIS
    }
  },
});

None of the solutions mentioned above worked for me. Instead, I opted to utilize the connection string method to apply PostgreSQL configurations. By setting the query parameter sslmode=no-verify, I was able to successfully establish the connection.

For example:

postgres://myuser:mypassword@myhost:5432/mydatabasename?sslmode=no-verify

This solution worked perfectly for me when configuring sequelize with a config.json file:

    "dialect": "postgres",
    "dialectOptions": {
      "ssl": {
        "require": true,
        "rejectUnauthorized": false
      }
    }

    "dialect": "postgres",

After trying various methods to access the database using Sequelize, I finally found success by following a note and setting a configuration variable.

If you encounter similar issues, consider omitting the ssl configuration object and instead specify the PGSSLMODE config var:

heroku config:set PGSSLMODE=no-verify.

When utilizing aws rds, the optimal approach to resolve this issue is by incorporating the certificates into the ssl configuration. To access the certificate bundle, you can currently obtain it from the documentation link provided here: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.SSL.html#UsingWithRDS.SSL.CertificatesAllRegions

If the hyperlink is no longer functional, perform a search for aws rds certificate or an equivalent term to locate it.

Here is the code snippet I utilized (I placed the pem file in the project root directory)

import { readFile } from "node:fs/promises";
import path from "node:path";

const rdsCa = await readFile(path.resolve(process.cwd(), "global-bundle.pem"));

export const db = new Sequelize(process.env.DATABASE_URL, {
    dialect: "postgres",
    dialectOptions: {
        ssl: {
           require: true,
           rejectUnauthorized: true,
           ca: [rdsCa],
        }
    }
}

This method can also be applied to other database providers that offer similar certificates.

For additional insights: I came across this information through a comment made by someone else, which directed me to a helpful blog post on the topic.
