This error is only thrown inside the internal connect and callback routes in Grant, and only when the provider was either misconfigured from the start or the session got lost during the OAuth flow redirects. Hope that helps.

@lancevo from your comment in SO:

I made a request to /connect/google/callback${query} per the example

This is internal route used by Grant only, and you should only use it when specifying the redirect URL of your OAuth App in the Google's web UI.

Probably you want to make request to this URL instead: /auth/${provider}/callback${search} found in the linked article on Medium.

@lancevo I had the same issue when I reproduced the tutorial wrote by @soupette! I figured out it's due to a small change we did a few weeks ago.

Set the host key to localhost instead of 127.0.0.1 in the ./config/environments/*/server.json file.

{
  "host": "localhost",
  "port": 1337,
  "autoReload": {
    "enabled": true
  },
  "cron": {
    "enabled": false
  }
}
