我试图创建最简单的日历应用程序，可以显示用户的Microsoft Outlook用户的日历事件。
我正在使用@azure/msal-node进行身份验证。
我正在使用GET https://graph.microsoft.com/v1.0/me/calendar/events获取事件
我能够进行身份验证并获得令牌，但在图形API请求中出现错误。
下面是我的代码：

const express = require('express');
const { PublicClientApplication, LogLevel } = require('@azure/msal-node');

// Initialize the MSAL client with your authentication configuration
const msalConfig = {
  auth: {
    clientId: process.env.CLIENT_ID,
    clientSecret: process.env.CLIENT_SECRET,
    authority: `https://login.microsoftonline.com/${process.env.TENANT_ID}`,
    redirectUri: 'http://localhost:3000/redirect'
  },
  system: {
    loggerOptions: {
      loggerCallback(loglevel, message, containsPii) {
        console.log(message);
      },
      piiLoggingEnabled: false,
      logLevel: LogLevel.Info
    }
  }
};

const msalClient = new PublicClientApplication(msalConfig);

// Create an Express app
const app = express();

// Define a route for initiating the login process
app.get('/login', async (req, res) => {
  const authCodeUrlParameters = {
    scopes: ['openid', 'profile', 'offline_access', 'Calendars.Read'],
    redirectUri: 'http://localhost:3000/redirect'
  };

  // Generate the authorization URL
  const authUrl = await msalClient.getAuthCodeUrl(authCodeUrlParameters);
  console.log('alok', authUrl)

  // Redirect the user to the authorization URL
  res.redirect(authUrl);
});

// Define a route for handling the redirect callback
app.get('/redirect', async (req, res) => {
  const tokenRequest = {
    code: req.query.code,
    scopes: ['openid', 'profile', 'offline_access', 'Calendars.Read'],
    redirectUri: 'http://localhost:3000/redirect'
  };

  try {
    // Acquire an access token using the authorization code
    const response = await msalClient.acquireTokenByCode(tokenRequest);

    const token = response.accessToken;
    const graphEndpoint = 'https://graph.microsoft.com/v1.0/me/calendar/events';
    const resp = await fetch(graphEndpoint, {
      headers: {
        Authorization: `Bearer ${token}`,
      },
    });
    const data = await resp.json();
    console.log('Calendar events:', data);
    res.send('Calendar events' + JSON.stringify(data));
  } catch (error) {
    // Handle the token acquisition error
    console.log(error);
    res.send('Authentication failed.');
  }
});

// Start the server
app.listen(3000, () => {
  console.log('Server started on http://localhost:3000');
});

我在图形API调用上得到响应

{
  "error": {
    "code": "OrganizationFromTenantGuidNotFound",
    "message": "The tenant for tenant guid 'd19680c7-8d06-4906-92bd-0e4c1b318f03' does not exist.",
    "innerError": {
      "oAuthEventOperationId": "213fd067-58a7-420a-bd93-64b4f68e6cae",
      "oAuthEventcV": "M17KB0OaSeGkiZmrisUKhA.1.1.1",
      "errorUrl": "https://aka.ms/autherrors#error-InvalidTenant",
      "requestId": "aee1392f-5824-432c-82ef-9083be5001af",
      "date": "2023-05-22T11:07:23"
    }
  }
}

我试图从Calendar endpoint returns OrganizationFromTenantGuidNotFound获得帮助，但仍然得到相同的错误。
我的clientId，clientSecret和authority是正确的，这就是为什么我能够得到令牌。
我错过了什么，所以在图形API调用中出错？
