Source code

• I provided exact source code that allows reproducing the issue locally.

import { test } from '@playwright/test';

test.describe('verify', async () => {
  test('test Case Name', async ({ page }) => {
    page.on('request', (request) => {
      if (request.method() === 'POST') {
        console.log(request.method());
        console.log(request.url());
        console.log(request.postData());
        console.log(request.postDataJSON());
        console.log(request.postDataBuffer());
      }
    });
    await page.goto('https://google.com');
    const inputs = await page.locator('[type="submit"]').all();
    await inputs[3].click();
  });
});

Steps

• [Run the test]

Expected
postData to return payload
postDataJSON to return payload
postDataBuffer to return payload

Actual
returns null

The test above returns null for postDataJSON() and for postDataBuffer() and for postData(). I also tried using page.WaitForRequest() to get the payload, but the same result, null instead of payload. I tried both Chromium and Firefox.

Looks like #6479

Yeah, it is, just found it after posting here. I am using RTK Toolkit in my project which is using request.clone(), and Chromium still didn't fix that issue.
