云函数 cloud.deleteFile 无法删除云存储中的文件？

const cloud = require('wx-server-sdk')   cloud.init()   exports.main = async (event, context) => {     let result = await cloud.deleteFile({ fileList: [event.val] })       return { ...result } }

返回结果：

{"fileList":[{"fileID":"cloud://masked.containername/wxe3973c4126f6ebef.o6zAJs4qRcdzUrocyafCXQ9Sl-f8.78oRqQxtEqH37f6c1b92421fa8c6f9e595ef9638a743.png","status":-503003,"errMsg":"storage file not exists"}],"errMsg":"deleteFile:ok"}

但存储中存在该文件ID：

请官方人员和遇到过类似情形的开发人员帮助，谢谢！
