sample/Interceptorexample.php dosnt Log anything

[sharkbit]

Line 9 has wrong libraries, should be:
use QuickBooksOnline\Payments\Interceptors{StackTraceLoggerInterceptor, RequestResponseLoggerInterceptor, ExceptionOnErrorInterceptor};

but that still dosnt get anything to log. It's like they are not being triggered. Using pretty much exact code from sample.
