node.js - （节点：9464）UnhandledPromiseRejectionWarning：错误 [ERR_HTTP_HEADERS_SENT]：在将标头发送到客户端后无法设置标头

Question

嗨，我正在尝试编写 mocha chai 测试来测试过期的 jwt 是否可以创建新条目

 it("Should NOT Allow user to create a new diary entry with an expired Token", done => {
  const entryTestData5 = {
    title: "diary",
    detail: "my new diary"
  };
  const token = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJmaXJzdE5hbWUiOiJmaXJzdE5hbWUiLCJsYXN0TmFtZSI6Imxhc3ROYW1lIiwiZW1haWwiOiJleGFtcGxlQGdtYWlsLmNvbSIsInJlbWluZGVyIjoib2ZmIiwiaWF0IjoxNTcxOTEyOTc2LCJleHAiOjE1NzE5MTI5Nzh9.2ETTnItxbaPJiAcDubq2fxSr6SXcPEo3VN8lcjVcl7M";
  chai
    .request(app)
    .post("/api/v1/entry")
    .set("auth", token)
    .send(entryTestData5)
    .end((err, res) => {
      expect(res).to.have.status(403);
      expect(res.body).to.have.property("message");
      done();
    });
});

我在尝试运行测试时收到以下警告

如果有人可以帮忙，请做

以下是我的服务器

import jwt from "jsonwebtoken";
import userModel from "../models/User";

async function checkToken(req, res, next) {
 const token = await req.headers.auth; 
 let InUserEmail;
 if (typeof token !== "undefined") { jwt.verify(token, process.env.SECRET, (err, result) => {
     if (err) {
       if (err.name === "TokenExpiredError") {
         return res.status(403).send({
           message: "TokenExpired"
         });
       }
     } else {
       InUserEmail = result.email;
       req.tokenData = jwt.verify(token, process.env.SECRET);
     }
   });
   const authUser = userModel.users.find(user => user.email === InUserEmail);
   if (!authUser) {
     return res.status(401).send({
       message: "not authorized to do the task"
     });
   } next();
 } else {
   res.status(403).send({
       message: "not authorized to do the task(forbidden)"
     });
}}
export default checkToken;
