Session cookie is not getting saved from Pantheon

Question

We are working on log in functionality with headless React and Pantheon with REST web services. When I send login request to Drupal site in localhost, it sets a session cookie in my browser. However, it doesn't do that for Drupal site deployed to Pantheon.

The cookie:

set-cookie: SSESS4ca8b3ff629fc50c99bed7678686=VYfXzM-S18y0n8PylU9HuHBVrEyZezRiwfirxB%2ClL; expires=Fri, 18-Nov-2022 18:14:03 GMT; Max-Age=2000000; path=/; domain=.oursitename.pantheonsite.io; secure; HttpOnly

Login request:

const body = {
      name: name,
      pass: pass,
    };
    const config = {
      headers: {
        "Content-Type": "application/json",
        "X-CSRF-Token": token,
      },
      withCredentials: true,
    };
    axios
      .post(
        `${process.env.REACT_APP_DRUPAL_URL}/user/login?_format=json`,
        body,
        config
      )

Update:

Cookie is getting stored in Mozilla browser, but not in Chrome.

Answer 1

You need to append STYXKEY to the cookie's name. Cookies without that prefix are stripped from the request at the edge in Pantheon
