Import the supplied namespace named "insomnia cookies"
Run the first request, a cookie is stored in the cookie jar and is usable in the second request. Wait 10 seconds (sometimes a little more) The cookie in the second call gets marked red and the request wont send
Re-run the first call, this should replace the cookie and it does, according to the cookie jar. It is however still not available to that second call.
Delete the cookie, run the first call. Cookie is now available again.
