使用微信开发者工具可以成功调用，但是切到真机调试报错：

Error: errCode: -404011 cloud function execution error | errMsg: cloud.callFunction:fail requestID , cloud function service error code -504002, error message Unexpected token { (callid 1593863088871-0.13276541170994327); at cloud.callFunction api; 

云函数代码：

// 云函数入口文件
const cloud = require('wx-server-sdk')

cloud.init()

// 云函数入口函数
exports.main = async (event, context) => {
  try {
    let result = await cloud.openapi.security.msgSecCheck({
      content: event.content
    });
    return result;
  }
  catch{
    return { errMsg: "openapi.security.msgSecCheck:fail", errCode: 1 };
  }
}

云函数调用权限config.json:

{
  "permissions": {
      "openapi": [
          "security.msgSecCheck",
          "security.imgSecCheck"
      ]
  }
}

调用代码：

wx.cloud.callFunction({
                        name: 'secCheck',
                        data: {
                            content: 'teste'
                        },
                        success: resp => {
                            console.log('contentValidate==>', resp);
                        },
                        fail: console.error
                    });

云函数在本地调试也可以通过，但是在云端调试也会报错：

user code exception caught, stackTrace:"Unexpected token {"
