warnAboutDataLoss fails with stringifying error and breaks application

[andreimatei]

I have a query set to poll every so often. When the query returns a particular result (an empty array), apollo client appears to fail in an internal function, and from that moment on the query does not appear to be polled any more. I'm sure ultimately I'm holding something wrong, but it appears that Apollo is not resilient to whatever it is that I'm screwing up. I think the error indicates that the String method is called on... something that doesn't support that.

The error comes from warnAboutDataLoss, which I assume is supposed to be an unessential method (although I am curious what it would tell me if it succeeded in printing a message).
