[tpktang]

when I run the command:

vcdl config store platform.driver <csv file name in config> <real file name> --csv

I got this error.

Do I need to edit the ini.py file in the MasterDriverAgent/masterdriver/interfaces ? by adding self.device_path

    def __init__(self, vip=None, core=None,device_path=None, **kwargs):
        # Object does not take any arguments to the init.
        super(BaseInterface, self).__init__()
        self.vip = vip
        self.core = core
        self.device_path = device_path

        self.point_map = {}
        
        self.build_register_map()
        

this one is the original one

    def __init__(self, vip=None, core=None, **kwargs):
        # Object does not take any arguments to the init.
        super(BaseInterface, self).__init__()
        self.vip = vip
        self.core = core

        self.point_map = {}
        
        self.build_register_map()
