oAuth2 Server + Custom Endpoints

Hello,

I use the oAUth2 Server Plugin.
So I want to create a custom endpoint that is protected with oAuth2.

When i try to POST data to the following route i get a 403 error even when I send the request with a valid token.

register_rest_route("foo/v1", "/foo", array(
		"methods" => "POST",
		"callback" => "foo",
		"permission_callback" => function() {
			return current_user_can("edit_other_posts");
		}
	));
