I noticed that since Saturday the REST API doesn’t return the expected answers.
To ensure that the access_token is valid, I refreshed it at https://online-go.com/oauth2/token/, the request to any REST API endpoint returns nothing or an
<h1>Server Error (500)</h1>
An example of how I encounter this using a curl command (shown here with a dummy access token), as documented in http://docs.ogs.apiary.io/#reference/authentication:
curl -H "Authorization: Bearer 324DASDfhXBvqFRdkjbHJTFDasdCJ9g" http://online-go.com/api/v1/me/notifications/
This worked before Saturday, did the API change?
