PHP warnings about count() on line 23 GeocodeResponse and no debug data

[goldhat]

I can't seem to get either a response, or even debug information from the PHP version of this. When I try the test.php it says OK on all tests including Mapbox authentication, so I think my token is fine. The only concern in the command line test is multiple warnings for count(): parameter must be an array or an object that implement Countable in GeocodeResponse.php on line 23. Every test results in this warning, and then "Doh" is output.

When I try to make the example request for San Francisco the response is just "null". I try debug mode, and still nothing is output. I try outputting some of the suggested other parts of the response like code, and I get a fatal error for instance:

Fatal error: Uncaught Error: Call to undefined method geocodeResponse::getCode() in C:\wamp64\www\skygearsolutions\wp-content\plugins\skygear-mapbox\skygear-mapbox.php on line 31

I am running this on a local machine, that's one thing I could think of that might interfere?
