为什么在真机上会有createWorker失败？

报错：

TypeError: Cannot read property ‘workerId’ of undefined at Object.createWorker (<anonymous>:2:1873544) at Object.p.(anonymous function) [as createWorker] (<anonymous>:2:874168) at Object.<anonymous> (<anonymous>:2:663304) at Object.<anonymous> (<anonymous>:2:1878762) at Object.<anonymous> (<anonymous>:2:1878892) at s (<anonymous>:2:120252) at Object.<anonymous> (<anonymous>:2:120718) at <anonymous>:23261:197 at require (<anonymous>:2:2200096) at <anonymous>:23262:10

在开发者工具上没有遇到，开发日志里频繁出现该报错

在app.js中使用

const worker = wx.createWorker('workers/request/index.js')
