node.js 的return执行问题

[iiifly]

}else if(data == '1'){
console.log('2:data:'+data);
return_msg='没有你想要听的这首歌';
let card = new Bot.Card.TextCard(return_msg);
console.log(return_msg);
return {
card: card,
outputSpeech: return_msg
};
}else{

node.js 在百度cfc下调用bot-sdk开发，第一个console.log可以正常返回，第二个console.log不显示信息，下面的return也不执行，请问这是什么原因

看看你页面是不是有什么错误信息
