    I am getting "CPLEX Error  1222: Duplicate entry." error. 

    How do I get more info related to the error? for example I would like to know what row or what variable was a duplicate. I am using the Python API.

    I have also attached the ".lp" file thats generated from model.write(' ')

    What is the function that throws this error? You will have to explicitly check the arguments of this function.
