node.js - 我的功能是在收到 params.finalemail 后不发送电子邮件

Question

我在 IBM 云函数中创建了一个函数来计算两个日期之间的夜数并发送电子邮件。夜数计算完美。Watson 发送 params.checkout 和 params.checkin 并返回总夜数。

当 Watson 发送 params.finalemail 时，params 会发送到云函数，但不会发送电子邮件。

我在 Watson 中设置它的方式是 2 个节点，第一个节点发送签入/签出，它运行良好。第二个节点发送 params.finalemail。但是邮件发不出去。

  sgMail.setApiKey('api')

  let msg = {}
  msg.to = '[e-mail]'
