Can not use Playwright to login on JS?

Question

const { test, expect } = require('@playwright/test');
test.only('Login 1', async ({ page }) => {
  await page.goto('my login page');
  await page.fill('input[name="userId"]', 'my userId');
  await page.fill('input[name="password"]', 'my password');
  await page.locator('#idPasswordInputForm a.input_area_btn_01').click({timeout: 30000});
})

I use above code to test login on my page automatically. However, after it runs to this line: await page.locator('#idPasswordInputForm a.input_area_btn_01').click({timeout: 30000}); on debug mode, It stuck on this step: waiting for scheduled navigations to finish.

Login on my page still works fine if I login manually.

Have I mistake something and how to fix it?
