定时触发配置文件单独上传了，都不行

需求是每隔一段时间自动触发云函数，但一直报错，要是不支持文档里就写清楚

config.json

{
    "permissions": {
        "openapi": ["subscribeMessage.send"]
    },
  "triggers": [
    {
      "name": "myTrigger",
      "type": "timer",
      "config": "*/5 * * * * * *"
    }
  ]
}

云函数：

const cloud = require('wx-server-sdk');
cloud.init({
    env: "oneyu"
  })
// cloud.init({
//     env: cloud.DYNAMIC_CURRENT_ENV
//   })
exports.main = async (event, context) => {
    const sendresult = await sendMsg();
    return sendresult;
};
async function sendMsg() {
    let thing1 = '标题';
    let character_string2 = "1000";
    let time3 ="2020-03-12 12:23";
    let depth ="23km";
    return await cloud.openapi.subscribeMessage.send({
        touser: 'touser',
        template_id: 'template_id',
        page: 'pages/xx/xx',
        data: {
        thing1: {
          value: thing1
        },
        character_string2: {
          value: character_string2
         },
        character_string4: {
          value: depth
        }
        }
    }).then((res) => res).catch((err) => err);
}
