OpenAPI Explorer 的demo运行不起来

OpenAPI Explorer 的demo运行不起来，赋值到小程序云开发中提示：

TypeError: Cannot read property 'Symbol(TIMER::READ_TIMER)' of null at D:\File\MiniProgramFile\txzn_Cloud\cloudfunctions\SMSLogin\node_modules\httpx\lib\index.js:190:41 at new Promise ( ) at Object.exports.read (D:\File\MiniProgramFile\txzn_Cloud\cloudfunctions\SMSLogin\node_modules\httpx\lib\index.js:180:10) at D:\File\MiniProgramFile\txzn_Cloud\cloudfunctions\SMSLogin\node_modules@alicloud\pop-core\lib\rpc.js:201:20 at processTicksAndRejections (internal/process/task_queues.js:97:5) at async u.exports.main [as handler] (D:\File\MiniProgramFile\txzn_Cloud\cloudfunctions\SMSLogin\index.js:30:5)

请问这个问题怎么解决？购买了短信服务接入不了。
