Model exported from Classification Learner doesn't work with the same data

I have exported several models, full and compact, from Classification Learner in order to use them in a workspace on new data. However, all of them throw the same error with training set and test set.

Unrecognized variable name 'predict_1'.

The exported code shows the name as a part of prediction vector, and it looks correct. The training code accepts both datasets, training and test... I couldn't find the way to fix this so far.

Thanks

Can you show the fragment of generated code that is leading to this message? Did you fit to a table with a variable predict_1, and does the table you are providing to the generated code also have a variable by this name?
