使用云函数调用msgSecCheck方法时会报错

代码如下：

// 云函数入口文件 const cloud = require('wx-server-sdk') const got = require('got')   let appid = ''; let secret = '';   let msgCheckUrl = 'https://api.weixin.qq.com/wxa/msg_sec_check?access_token='; let tokenUrl = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='+appid+'&secret='+secret   cloud.init()   // 云函数入口函数 exports.main = async (event, context) => {   let tokenResponse = await got(tokenUrl)   let token = JSON.parse(tokenResponse.body).access_token;     // 文本内容检测接口拼接 access_token 值, JSON.stringIfy 将值转换成 JSON 字符串   let checkResponse = await got(msgCheckUrl + token, {     body: JSON.stringify({       content: event.text     })   });   return checkResponse.body

报错如下：

Uncaught (in promise) Error: errCode: -404011 cloud function execution error | errMsg: cloud.callFunction:fail cloud function service error code -504002, error message incorrect header check; at cloud.callFunction api;
