我在使用nodemailer时遇到问题-我在Firebase中的Cloud Functions中使用了它，在创建数据后，我发送了电子邮件确认（我使用的是Blaze计划，所以这不是问题）。它已经工作了两天，突然间：

我也在Firebase控制台日志中收到此错误：Function returned undefined, expected Promise or value。
功能如下：
transporter.sendMail(mailOptions, (error, info) => { // TODO should be returned
if (error) {
return console.log(error);
}
console.log('Message %s sent: %s', info.messageId, info.response);
//move it elsewhere - maybe HTTP trigger?
return admin.database().ref('events/' + event.data.val().eventKey).remove();
});
