Error: self-signed certificate in certificate chain

Help

Hi,

I am getting a 500 runtime error on my webapp made with Nextjs (v14.2.16) + drizzle-kit & drizzle-orm + @vercel/postgres running on Supabase DB.

Here’s the stack trace:

Unexpected error: Error: self-signed certificate in certificate chain

<!-- Current versus Expected behavior -->

I’ve tried to use this as per recommendation from cursor but no success:

const pool = new Pool({
	connectionString: process.env.POSTGRES_URL,
	ssl: {
		rejectUnauthorized: false, // This allows self-signed certificates
	},
});

I’ve also tried the fix as per discussion here Error: self signed certificate in certificate chain · drizzle-team/drizzle-orm · Discussion #881 · GitHub

This is my drizzle.config.js:

import 'dotenv/config';
import { defineConfig } from 'drizzle-kit';

if (!process.env.POSTGRES_URL) {
	throw new Error('POSTGRES_URL environment variable is required');
}

if (!process.env.DATABASE_CA) {
	throw new Error('DATABASE_CA environment variable is required');
}

export default defineConfig({
	out: './db/migrations',
	schema: './db/schema.ts',
	dialect: 'postgresql',
	dbCredentials: {
		// url: `${process.env.POSTGRES_URL!}?sslmode=no-verify`,
		url: process.env.POSTGRES_URL!,
		ssl: { ca: process.env.DATABASE_CA },
	},
});

and this is how I connect to PostgreSQL:

// Create a PostgreSQL pool using connection string from environment variables
const pool = new Pool({
	connectionString: process.env.POSTGRES_URL,
	ssl: {
		rejectUnauthorized: false, // This allows self-signed certificates
	},
});
const db = drizzle(pool, { schema });

Hello,

//drizzle.config.ts
dbCredentials: {
        // using url doesn't work because it seems to override the ssl config
        // url: process.env.DATABASE_URL!,
        host: process.env.DATABASE_HOST!,
        port: parseInt(process.env.DATABASE_PORT!),
        user: process.env.DATABASE_USER!,
        password: process.env.DATABASE_PASSWORD!,
        database: process.env.DATABASE_NAME!,
        ssl: { ca: process.env.DATABASE_CA! },
    },

make sure you’re not using url, and set up the individual connection url components instead
