re>

似乎刷新重绘的时候出现的问题，日志显示的代码行对不上；想咨询下这种异常会是什么原因导致的？

Can not get Prototype on non ECMA Object 常见场景是发生在napi_value生存期，原因可能是napi_value超出NAPI框架的scope，定位的话可以根据崩溃栈反编译找到出现问题的napi接口的上层接口，在上层接口内找到出问题的napi_value，检查napi_value的使用范围是否超出了napi_handle_scope的作用域范围。按这种方式重新试一下定位问题。

在HarmonyOS鸿蒙Next环境中遇到“TypeError: Can not get Prototype on non ECMA Object”错误，通常表明你试图在一个非ECMAScript对象上访问其原型（Prototype）。这种错误可能由以下几种情况引起：

  1. 对象类型不匹配：你尝试对一个原生（非JavaScript）对象执行ECMAScript对象的操作。在鸿蒙系统中，某些API或模块返回的对象可能并非标准的ECMAScript对象。

  2. API使用不当：在调用鸿蒙API时，可能误用了返回的对象，比如尝试在一个不支持Prototype属性的对象上调用相关方法。

  3. 环境差异：鸿蒙系统的JavaScript环境可能与标准的浏览器环境有所不同，导致某些在浏览器中可行的操作在鸿蒙环境中不可行。

针对此错误，你需要检查引发问题的对象来源，确认其是否为ECMAScript对象。如果是鸿蒙API返回的对象，请查阅相关文档，确认该对象是否支持Prototype操作。此外，确保你的代码逻辑符合鸿蒙系统的运行规则。
