title: NodeJS discord bot commands getting error Cannot send an empty message
body: <p>I am making a discord bot and one of my commands is not working. I want the bot to copy what the user said in the command but I am getting the Error: <strong>UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): DiscordAPIError: Cannot send empty message</strong>
  and I also tried using console.log() but that was empty too so I know something is wrong but i'm just not sure what is. </p>
  
  <pre><code>case "say":
      if(!args[1] == " "|| !args[1] == ""){
      //  message.channel.sendMessage(args[1]);
        words = [];
        for(i=0;i==args.length-1;i++){
          words.append(args[i]);
        }
        var wordsString = words.join(" and ");
        console.warn("Bot said: "+wordsString);
        message.channel.sendMessage(wordsString);
      }
  break;
  </code></pre>
