A runtime exception is raised by the rule Common.core.2016 (Object reference not set to an instance of an object.) when validating the northwind service
in crawling mode.
I'm using the latest version (2012 January 27). I guess the online version has the same error because there I can see that only 21 of 22 rules have been executed (Section Metadata document).
Could you please check?
Thanksa and regards
