I can not extract the class to predict in the "Document Data Extractor

Hi, like is shown on the prints, i had defined the DIAGNOSTICO column as class to predict, but when i process the workflow on the node “Document Data Extractor” my class is empty, can anyone help me??
Sorry for my english


from what I can see in the screenshots the settings look correct. One thing that you can try is to use the Category to Class node instead of the Document Data Extractor. If this doesn’t work, I can take a look at the other settings, if you upload the workflow (maybe with a sample of the data).
