## 根因

在React组件渲染期间抛出了未处理的JavaScript错误（例如TypeError、ReferenceError），React记录组件堆栈跟踪以帮助定位源。

## 解决方案

1. ```
   Implement an error boundary component using componentDidCatch or static getDerivedStateFromError to catch rendering errors and display a fallback UI.
   ```
2. ```
   Use the component stack trace to identify the failing component and fix the underlying error (e.g., null check, type validation).
   ```

## 无效尝试

- **Adding a try-catch inside the render function to suppress the error** — try-catch in render does not catch errors thrown by React's reconciliation process or child components; it only catches errors in the synchronous code. (80% 失败率)
- **Ignoring the component stack and only looking at the original error** — The component stack is crucial for identifying which component caused the error; ignoring it makes debugging much harder. (60% 失败率)
- **Using a global window.onerror handler to log errors** — Global handlers do not prevent the error from crashing the React tree; they only log it. The error still propagates. (50% 失败率)
