Node.js 将pathParameters正确发送到AWS Lambda NodeJS函数-从AWS控制台调用可以工作，但不能从浏览器/邮递员调用

我有一个NodeJS lambda函数，当从AWS控制台测试时可以工作，但当从浏览器或邮递员返回时，

“无法读取未定义的属性“id”

这是我在AWS控制台测试功能时用作测试事件的值：

{
  "pathParameters": {
    "id": "gamuda"
  }
}

我添加了console.log以查看上建议的“event”值，并注意从浏览器/邮递员调用时没有读取该值

如何正确读取该值？这是我的代码：

const id=event.pathParameters.id

module.exports.exportContactsByClientID = (event, context, callback) => {
  console.log(event);
  const id = event.pathParameters.id;
  // const id = 'mkh';
  
  const params = {
    TableName: contactsTable,
    IndexName: "client_code-created_at_local-index",
    KeyConditionExpression: "client_code = :v_ID",
    ExpressionAttributeValues: {
      ":v_ID": id,
    },
    ProjectionExpression: "client_code, created_at, contact_name, age, phone, email, dsr_ratio, max_eligibility, selected_banks"
  };

return db.query(params)
.promise()
.then((res) => {
  // console.log(res);
  const items = res.Items;
  // Headers + Columns
  worksheet.cell(1, 1).string('Client').style({font: {bold: true}});
  worksheet.cell(1, 2).string('Name').style({font: {bold: true}});
  worksheet.cell(1, 3).string('Age').style({font: {bold: true}});
  worksheet.cell(1, 4).string('Email').style({font: {bold: true}});
  worksheet.cell(1, 5).string('Phone').style({font: {bold: true}});
  worksheet.cell(1, 6).string('DSR Ratio').style({font: {bold: true}});
  worksheet.cell(1, 7).string('Max Eligibility').style({font: {bold: true}});
  // Rows
  // items.sort((a, b) => (a.date > b.date) ? -1 : 1);
  items.forEach((item, i) => {
    console.log(item.contact_name);
    worksheet.cell(i + 2, 1).string(item.client_code);
    worksheet.cell(i + 2, 2).string(item.contact_name);
    worksheet.cell(i + 2, 3).string(item.age);
    worksheet.cell(i + 2, 4).string(item.email);
    worksheet.cell(i + 2, 5).string(item.phone);
    worksheet.cell(i + 2, 6).string(item.dsr_ratio);
    worksheet.cell(i + 2, 7).string(item.max_eligibility);
  });
  console.log(contactsBucket);
  console.log(id);
  return workbook.writeToBuffer().then(buffer => {
    console.log('inside writetoubgger')
    var params = {
      Bucket: contactsBucket,
      Key: `contacts/${id}.xlsx`,
      Body: buffer,
      ACL: 'public-read'
    }
    // S3.upload(params, function(err, data) {
    //   if (err) {
    //     console.log(err, err.stack);
    //   } else {
    //     // callback(null, response(200, res));
    //     callback(null, response(200, res));
    //   }
    // });
    return S3.upload(params).promise().then(data => {
      callback(null, response(200, res));
});
  })
})
.catch((err) => callback(null, response(err.statusCode, err)));
};

当通过id获取联系人时，我在读取id时使用类似的方法，此功能工作正常：

module.exports.getContactsByClientID = (event, context, callback) => {
  const id = event.pathParameters.id.toLowerCase();
  const newDt = new Date();
  const filterDt = new Date(newDt.getTime() - (newDt.getTimezoneOffset() * 60000 )).toISOString().split("T")[0];

  var params = {
    TableName: contactsTable,
    IndexName: "client_code-created_at_local-index",
    KeyConditionExpression: "client_code = :v_ID AND created_at_local = :v_created",
    ExpressionAttributeValues: {
      ":v_ID": id,
      ":v_created": filterDt
    },
    ProjectionExpression: "client_code, contact_name, age, phone, email, dsr_ratio, max_eligibility, selected_banks"
  };

return db.query(params)
.promise()
.then((res) => {
  console.log(res);
  callback(null, response(200, res));
})
.catch((err) => callback(null, response(err.statusCode, err)));
};

我已经做了一整天了，可能错过了一些愚蠢的事情：（任何提示和指导都将不胜感激。
我的问题与API网关上的设置有关。以前
export/{id}
没有选中“使用Lambda代理集成”选项（因为我正在测试一些东西）

正如指南所说，这需要进行检查，以便我们的请求详细信息可以在活动中获得

还有一个问题-为什么我在AWS控制台上的测试没有失败
