Google Analytics hit request rejected with status code HTTP/1.1 200 no error

I think this warning is not accurate, at least in my case (tvOS platform) the response is 200 no error, and the event appears in GA dashboard.

I use GAV3 and I don't see why it should have the OK too, there are other cases? If yes I could not find them on GA dev documentation.
if (request.responseHeaders ["STATUS"].Contains("200 OK"))

Happens on Unity3d - WebGL platform too, it works but it throws a warning.
