【报Bug】unicloud-db 使用loadtime失效，数据没加载就开始执行

• 使用环境：微信小程序
• hbuilderx版本：3.8.12.20230817

以下是我的代码，详细的报错截图在附件中。报如下错误：

• [Vue warn]: Property "swhere" was accessed during render but is not defined on instance.
• vendor.js? [sm]:3106 TypeError: Cannot read property 'details' of undefined

经过我的分析，感觉是loadtime失效，数据还没有加载就开始执行unicloud-db
