Recently I got the following JavaScript console error on Google Chrome for my mapkit.js implementation. Essentially the same message occurs on Firefox, but it's only a warning. Can anyone please help? Is the issue on my server https://example.com or is it at the Apple MapKit JS service end? Am I doing something wrong? Is this enough information?
