What am I doing wrong with migrations?

import * as mysql from "mysql2/promise";
import { MySql2Database, drizzle } from "drizzle-orm/mysql2";
import { migrate } from "drizzle-orm/mysql2/migrator";
import { getEnv } from "./env";

export let db: MySql2Database<Record<string, never>>;

export async function initializeDatabase() {
    const env = getEnv();
    const connection = await mysql.createConnection({
        host: env.database.host,
        user: env.database.user,
        password: env.database.pass,
        database: env.database.db,
    });

    const db = drizzle(connection);

    // Currently crashing the app startup for me, check out manual migration in npm scripts (npm run drizzle:push:dev)
    await migrate(db, { migrationsFolder: "./db/migrations" });
}

import { defineConfig } from "drizzle-kit";
import { getEnv } from "@/env";
const env = getEnv();

export default defineConfig({
    schema: "./db/schema.ts",
    driver: "mysql2",
    out: "./db/migrations",
    dbCredentials: {
        user: env.database.user,
        password: env.database.pass,
        host: env.database.host,
        database: env.database.db,
    },
    verbose: true,
    strict: true,
});
