GOOSE Python code: error assigning values to dstAddress

[kwasibb]

Hello, I tried to write a Python version of the goose_publisher_c in the examples folder but I get an error trying to assign a value to the dstAddress field. I am sure that I am missing something. Kindly assist, thank you. The error and code are below:

Traceback (most recent call last):

Have you try this API? : iec61850.CommParameters_setDstAddress();

as the following example:

    gooseCommParameters = iec61850.CommParameters()

    gooseCommParameters.appId = app_id;
    iec61850.CommParameters_setDstAddress(gooseCommParameters,
                                          address[0],
                                          address[1],
                                          address[2],
                                          address[3],
                                          address[4],
                                          address[5])
    gooseCommParameters.vlanId = vlan_id;
    gooseCommParameters.vlanPriority = priority;

    publisher = iec61850.GoosePublisher_create(gooseCommParameters, interface)
