(in promise) MiniProgramError 是什么原因？

之前正常使用，今天小程序在手机上忽然打不开了，显示报错：

(in promise) MiniProgramError

Invalid attempt to destructure non-iterable instance.

In order to be iterable, non-array objects must have a [Symbol.iterator]() method.

TypeError: Invalid attempt to destructure non-iterable instance.

请问是什么原因？
