我正在尝试在Node.Js上调用QuickBook的API，但是却出现了以下错误

Question

代码：

const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const OAuthClient = require('intuit-oauth');

app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

const urlencodedParser = bodyParser.urlencoded({ extended: false });
oauthClient = new OAuthClient({
    clientId: 'ABmWLisPCBmxAXMM24r7HK6wK8lWpWOlybWSinDUAkW0l3FZsj',
    clientSecret: '4SRQWIXv547bUKuyDk7xxw1YIRTLddXJA11f2zhc',
    environment: 'sandbox',
    redirectUri: 'http://localhost:8000/callback', //We have to add callback URL to quickbooks dashboard
});
app.get('/authUri', urlencodedParser, function (req, res) {
   
  
    const authUri = oauthClient.authorizeUri({
        scope: [OAuthClient.scopes.Accounting],
        state: 'intuit-test',
    });
    res.send(authUri);
    // Here we start the authentication process
});

app.get('/callback', function (req, res) {
    oauthClient
        .createToken(req.url)
        .then(function (authResponse) {
            oauth2_token_json = JSON.stringify(authResponse.getJson(), null, 2);
            console.log("Token:", oauth2_token_json)
            res.send(oauth2_token_json);
        })
        .catch(function (e) {
            console.log("ERR:",e);
            res.send(e);
        });
        //Here we recieve the token succesfully or get the error. 
});

app.listen(8000,()=>{
    console.log('i am running');
});


const body = {
    "Line": [
      {
        "DetailType": "SalesItemLineDetail", 
        "Amount": 100.0, 
        "SalesItemLineDetail": {
          "ItemRef": {
            "name": "Services", 
            "value": "1"
          }
        }
      }
    ], 
    "CustomerRef": {
      "value": "1"
    }
  
};

oauthClient
    .makeApiCall({
    url: 'https://sandbox-quickbooks.api.intuit.com/v3/company/4620816365092507370/invoice?minorversion=55',
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
    },
    body: JSON.stringify(body),
    })
    .then(function (response) {
    console.log('The API response is  : ' + response);
    })
    .catch(function (e) {
    console.log('The error is ' + JSON.stringify(e));
});

错误：

错误是：
