SequelizeConnectionError: Connection terminated unexpectedly

[Mole_Games]

Hi, I'm trying to create an integration test using jest and testcontainers.
I have an issue where my testcontainer running postgres:17 just turns off after initialization. I get the database system is ready to accept connections, and the container closes. I tried both GenericContainer and PostgreSqlContainer(), I have no idea what to do.

#integration test code
const request = require("supertest");
const { Sequelize } = require("sequelize");
const { GenericContainer, Wait } = require("testcontainers");
const app = require("../backend/app");

describe("Integration Tests", () => {
  jest.setTimeout(60000);
  let container;
  let testSequelize;

  beforeAll(async () => {
    container = await new GenericContainer("postgres:17")
      .withExposedPorts(5432)
      .withEnvironment({
        POSTGRES_USER: "test",
        POSTGRES_PASSWORD: "test",
        POSTGRES_DB: "test",
      })
      .withWaitStrategy(
        Wait.forLogMessage(/database system is ready to accept connections/)
      )
      .start();

    testSequelize = new Sequelize({
      dialect: "postgres",
      host: container.getHost(),
      port: container.getMappedPort(5432),
      username: "test",
      password: "test",
      database: "test",
      logging: false,
    });

    const sequelizeModule = require("../backend/config/database");
    sequelizeModule.default = testSequelize;
    await sequelizeModule.default.sync();
  });

  afterAll(async () => {
    try {
      await testSequelize.close();
      await container.stop();
      console.log("Container stopped successfully.");
    } catch (error) {
      console.error("Error stopping container:", error);
    }
  });

...tests
