我让它在本地工作，但得到一个响应错误：未经授权在Vercel。
我已经在Sendgrid上创建了一个已验证的单个发件人验证。
我尝试在Sendgrid上创建一个新的API密钥，但它仍然不起作用。
我别无选择。
这是我在API路径中的代码：

import type { NextApiRequest, NextApiResponse } from "next";
const sgMail = require("@sendgrid/mail");

type EmailData = {
  to: string;
  from: string;
  subject: string;
  text: string;
  html: string;
};

type DataResponse = {
  data?: any;
  success: boolean;
  error?: string;
};

const emailAddress = process.env.SENDGRID_EMAIL as string;
const emailAddressTo = process.env.SENDGRID_EMAIL_TO as string;

sgMail.setApiKey(process.env.SENDGRID_API_KEY as string);

export default async function _(req: NextApiRequest, res: NextApiResponse<DataResponse>) {
  if (req.method !== "POST") {
    res.status(400).json({ success: false, error: "Invalid request" });
    return;
  }

  const data = JSON.parse(req.body);
  const { name, email, phone = "", message = "" } = data;

  console.log("sgMail", sgMail);
  console.log("--------------");
  console.log("process.env.SENDGRID_API_KEY", process.env.SENDGRID_API_KEY);
  console.log("--------------");
  console.log("SENDGRID_EMAIL", process.env.SENDGRID_EMAIL);
  console.log("--------------");
  console.log("SENDGRID_EMAIL_TO", process.env.SENDGRID_EMAIL_TO);
  console.log("--------------");

  const text = `
  Name: ${name} \r\n
  Email: ${email} \r\n
  Phone: ${phone} \r\n
  message: ${message} \r\n
`;

  let emailData: EmailData = {
    to: emailAddressTo,
    from: emailAddress,
    subject: "Form submission",
    text: text,
    html: `<div>${text.replace(/\r\n/g, "<br>")}</div>`,
  };

  try {
    await sgMail.send(emailData);
  } catch (error) {
    console.log(error);
    res.status(400).json({ success: false, error: "Error while sending email" });
    return;
  }

  res.status(200).json({ success: true, data: {} });
}

这是来自服务器的日志，其中包含以下错误消息：
