Response body, read from the service source

The route declares IEnumerable<object>. object is the C# base type, so the code states that a body is returned and declines to say what is in it — the shape is chosen at runtime, and the body is a JSON array whose elements need not share a shape. That is the declaration, not a failure to read it, and nothing here narrows it.
