I'm attempting to delete a facebook story/action, like so:

curl -F 'access_token=[valid_token]' -X DELETE https://graph.facebook.com/[action_id]

Facebook is responding with an internal server error, like so:

{"error":
  {"message":"An unexpected error has occurred. Please retry your request later.",
      "type":"OAuthException","code":2}}

Is this an error caused by my actions, or something on Facebook's end?

Additional info

When I run

curl -X GET https://graph.facebook.com/[action_id]?access_token=[valid_token]

the result is "false"
