Error while apply model for unseen data

HeikoeWin786

Hello all,

I am testing the NBC in cross-validation to understand throughly.
I am aware that the train dataset and test dataset needs to follow the same data pre-processing process.
However, when I take the exe of cross-validation and input the exe of pre-processed data (from unseen dataset), I got the error below.
Could you please advise me where I made a mistake here?
I had attached my rmp file and error message for your kind reference. 

Thanks much in advance.
