When i am trying to train the model in document intelligence, if i’m extract the field values of net weight, gross weight and Values the model will be failed and i’m getting the following error..

Could not build the model: Can’t find any valid labels for provided dataset. Labels file SamplePLPATH/PL-31-24.pdf is invalid for the following reason(s): ‘Field plvtrade has labels with undefined subfields.’ Labels file SamplePLPATH/PACKING LIST-24.pdf is invalid for the following reason(s): ‘Field plvtrade has labels with undefined subfields.’ Labels file SamplePLPATH/PL-31-24 – Copy.pdf is invalid for the following reason(s): ‘Field plvtrade has labels with undefined subfields.’ Labels file SamplePLPATH/PACKING LIST- Vtrade-12-24.pdf is invalid for the following reason(s): ‘Field plvtrade has labels with undefined subfields.’ Labels file SamplePLPATH/PACKING LIST-24 – Copy.pdf is invalid for the following reason(s): ‘Field plvtrade has labels with undefined subfields.’
