[BUG] Edge does not report request payload

[ethanwc]

Hi,
I am trying to verify expected data is being sent to an api. I am able to access the response data, but not the request data. How do you grab the request payload data inside playwright? I am calling request.postDataJson() which is returning null.
I created an example to demo my issue, and I ran into the same thing for post request on google.com.

const { getEdgePath } = require("edge-paths");

(async () => {
  const browser = await chromium.launch({headless: false, devtools: true, executablePath: getEdgePath() });
  const page = await browser.newPage();
  const [loadRes] = await Promise.all([
    page.waitForRequest(req => req.url().startsWith("https://browser.events.data.msn.com/OneCollector")),
    await page.goto("https://ntp.msn.com/edge/ntp?locale=en&dsp=1&sp=Bing&query=enterprise")
  ]);

   console.log(loadRes.url());
   console.log(loadRes.postDataJSON());
  await browser.close();
})();

(async () => {
  const browser = await chromium.launch({headless: false, devtools: true, executablePath: getEdgePath() });
  const page = await browser.newPage();
  const [loadRes] = await Promise.all([
    page.waitForRequest(req => req.url().startsWith("https://play.google.com")),
    await page.goto("https://google.com")
  ]);

   console.log(loadRes.url());
   console.log(loadRes.postDataJSON());
  await browser.close();
})();

Thanks @ethanwc. I'm able to repro with the following script. It seems that none of the requests to browser.events... return a post body, but if I see the same request in browser dev tools, I can see "request payload".

This is on Edge version 87.0.654.0 (Official build) Dev (64-bit). This url doesn't work in plain Chromium and I wonder if the browser is behaving differently for this particular url.

const { chromium } = require('playwright');
const { getEdgePath } = require("edge-paths");

(async () => {
  const browser = await chromium.launch({
    headless: false, devtools: true, executablePath: getEdgePath()
  });

  const page = await browser.newPage();
 
  page.on('request', request => {
    if (request.url().includes('browser.events'))
      console.log(request.postData())
  });

  await page.goto("https://ntp.msn.com/edge/ntp?locale=en&dsp=1&sp=Bing&query=enterprise");
  await page.waitForTimeout(50000);
  await browser.close();
})();

The snippet from @arjunattam works for me with Edge 87.0.664.41 on MacOS 10.15. Did the issue fix itself on your end?
