Hi, I tried running this same process in several environments. I was successfully able to run them yesterday and last week. But today for some reason, when I went to run it, it no longer seems to be the case. I get an error that the input [ExampleSet does not match the training ExampleSet. Missing Attribute: 'accessori']. Any good method for debugging? I've tried refreshing and going to older versions of the code and no luck. The process stops at the "Apply Model" phase. 

Attached the xml. Thanks.
