使用sendGrid API时未定义要求

如何解决使用sendGrid API时未定义要求

在执行我的代码时，我不断收到“要求未定义”错误消息。有谁知道为什么会这样？

    SENDGRID_API_KEY =
//   "api key here";

const sgMail = require("@sendgrid/mail");
sgMail.setApiKey(process.env.SENDGRID_API_KEY);

const msg = {
  to: "test.account@gmail.com",// Change to your recipient
  from: "test2.account@gmail.com",// Change to your verified sender
  subject: "Sending with SendGrid is Fun",text: "and easy to do anywhere,even with Node.js",html: "<strong>and easy to do anywhere,even with Node.js</strong>",};

sgMail
  .send(msg)
  .then(() => {
    console.log("Email sent");
  })
  .catch((error) => {
    console.error(error);
  });
