OnAuth method will trigger twice

Hi all,
When I return false in onauth method, the console will output twice and the client will execute onError twice. Is this normal? thanks!

    //server side
    async onAuth(client: Client, options: any){
        console.log("onauth------------")
        return new Promise.reject({message:"fail message"})
    }

  //server side console print twice
  "fail message"
  "fail message"

  //client side onError will trigger twice
   "fail message"
   ""   //the second err message is null string

Hi @BlueBang, thanks for reporting, this sounds like a bug in the printing / error reporting, I'm pretty sure things are executing only once, though. I'll have a look at this soon
