[BUG] Mocking GQL calls does not work - route.request().PostData(), route,fetch() not working for chromium

• Other info: Firefox works

Source code

Just trying to do as simple as mocking all Graph QL calls so that I can identify which one is mine and mock that.

await page.route(**/graphql', async (route) => {
    console.log({postData:JSON.parse(route.request().postData() as string)}) => null 
    console.log({postDataJSON:route.request().postDataJSON()}) => null

    const response = await route.fetch(); => 400 error
    console.log({response});
    const json = await response.json();
    console.log({json});

    await route.fulfill({ response, json });
  });

In Firefox it all works like a charm.

Found some other issues related to this
Looks like still related to
Chromium Bug

If its still indeed a chromium issue, is there a workaround for identifying one graphQL call and mocking that one, and continuing the rest untouched?

Thanks

Unfortunately there is no way currently to discriminate such requests based on post data. You could try changing the sending code to add some header or a url param, but that would require changing the app code.

Merging the report into #6479, please upvote that one instead.
