Custom extraction model - training model error due to 'Field items has labels with undefined subfields.'

Frane Mestrovic 10

I labeled my custom extraction model, but the model training fails every time due to the following error: 'Field items has labels with undefined subfields.'

@Frane Mestrovic Could you please add screen shot of your label data screen from form recognizer studio? It looks like the labels on the right-hand side of the screen which are used or marked on the document do not have a subtype defined for one or some of them.

Usually, when you add a label a default subtype is specified. But in this case, it seems like the mapping or labeling was incorrect causing this error. Please try to verify if you have used the label against the correct text in your document and retry the training. You might also try to delete the label and re-add the same if it can be done with minimal effort. I hope this helps!! Thanks!!

@Frane Mestrovic Did you get a chance to review if any of the labels need correction?

The error message "Field items has labels with undefined subfields" indicates that there is a problem with the labels you have created for your custom extraction model. Specifically, it means that you have created a label for a field that has subfields that are not defined. To resolve this error, you need to ensure that all subfields are defined for each field in your labels.

You can check your labels by going to the labeling window and selecting the "Fields" tab. From there, you can expand each field to see its subfields and ensure that they are all defined. Once you have made any necessary updates to your labels, you can try training your model again.
