Fb::Auth#revoke seems not working

[kangkyu]

Fb::Auth.new(refresh_token: ACCESS_TOKEN).revoke

returns an error

Fb::HTTPError: Error validating access token: The session has been invalidated because the user changed their password or Facebook has changed the session for security reasons.

it runs this request by the way

curl -X DELETE "https://graph.facebook.com/v2.9/me/permissions?access_token=ACCESS_TOKEN"

This might be a problem with the user access token (ACCESS_TOKEN). It works when a new token is used.
