Coder error using codegen: Directly accessing field or property of nonscalar struct or object not supported for code generation.

I have saved my trained SVM model using saveLearnerforCoder, and am trying to generate fixed point C code using codegen. However, I get the abover error using codegen.

saveLearnerForCoder(classificationSVM,'Classifier_FP');

generateLearnerDataTypeFcn('Classifier_FP',predictor_data);

T = Classifier_FP_datatype('Fixed')

X_fx = cast(predictor_data,'like',T.XDataType);

codegen EntryPointFcn -args {X_fx,coder.Constant(T)}

The error points to the line validateattributes in a built in function validateFields(Instr). How can I fix this issue?
