Got it👍
That error is coming from the Postgres client (pg) when Drizzle tries to apply migrations. The key part
is:
vbnet
SASL: SCRAM-SERVER-FIRST-MESSAGE: client password must be a string
This means your database password is either not being passed correctly, or it's not a string
(possibly undefined, null, or a number).
Common causes & fixes:
1. Check your .env or config

env
DATABASE_URL=postgres://user:password@localhost:5432/dbname
Make sure password is a proper string.
No surrounding quotes unless part of the password.
If password has special characters (@, #, :), they must be URL encoded.
Example:
Password is My@Pass#123 → URL should be:
perl
postgres://user:My%40Pass%23123@localhost:5432/dbname
2. Check your drizzle.config.ts
If you’re using something like:
ts
import { defineConfig } from "drizzle-kit";
export default defineConfig({
schema: "./src/schema/*",
out: "./drizzle",
driver: "pg",
dbCredentials: {
connectionString: process.env.DATABASE_URL!,
},
});
Make sure process.env.DATABASE_URL is actually loaded. Try logging it:
ts
console.log("DATABASE_URL:", process.env.DATABASE_URL);
If it prints undefined, you need to load dotenv:
ts
import "dotenv/config";
3. If using separate credentials instead of a URL
ts
dbCredentials: {
user: process.env.DB_USER!,
password: process.env.DB_PASSWORD!, // must be a string
host: process.env.DB_HOST!,
port: Number(process.env.DB_PORT || 5432),
database: process.env.DB_NAME!,
}
Make sure you’re not accidentally passing a number (e.g., password=12345 without quotes in .env).

✅ Quick test:
Run in Node REPL inside your project:
js
require("dotenv").config();
console.log(typeof process.env.DB_PASSWORD, process.env.DB_PASSWORD);
If it logs undefined or anything other than "string", that’s the problem.
Do you want me to help rewrite your drizzle.config.ts in a safe way that ensures the password is
always treated as a string?
