On February 11th your application (Laravel Forest) used an access token (with the User-Agent GuzzleHttp/6.5.1 curl/7.64.0 PHP/7.3.5) as part of a query parameter to access an endpoint through the GitHub API: https://api.github.com/user
Please use the Authorization HTTP header instead as using the access_token query parameter is deprecated and will be removed July 1st, 2020.
