}

Invoke from RPC:

{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "invokefunction",
    "params": [
        "0xc04ff111aa88cc5239cf36360cb298a9a3eae586",
        "myMethod",
        []
    ]
}

Response body:

{
    "jsonrpc": "2.0",
    "id": 1,
    "result": {
        "script": "wh8MCG15TWV0aG9kDBSG5eqjqZiyDDY2zzlSzIiqEfFPwEFifVtS",

        "notifications": [],
        "stack": [
            {
                "type": "InteropInterface",
                "interface": "IIterator",
                "id": "0cd0591b-cf5a-4517-a060-779269f3577d"
            }

    }
}

Invoke again from RPC to get the specific value of the iterator. For more information, refer to the command traverseiterator .
