OKEX analog drive not available

OKEX's analog drive is the V5 API, deploying a host on its own VPS (which is the latest version), and running APIs such as GetAccount will return the following error: {error_message:Please change to port v1 when you are using v1 apiKey. If you wish to use port v3, please register a v3 apiKey.按照API文档设置exchange.IO("simulate", true), will return an error Futures_OP 4: argument error, still not available The code to execute is as follows: function main (() {exchange.IO("simulate", true); Exchange.SetTimeout ((2000)); and Log ((exchange.GetAccount))); I'm not sure. If any of the inventor's officials see it, please let me know if the problem is that the platform is not supported or something else.
