I found a similar unsolved discussion regarding build errors in the lobe-chat project: [为什么npm run build打包会有如下报错呢](https://github.com/lobehub/lobe-chat/discussions/6947), which was last updated on March 15, 2025 ^{[[1]](https://github.com/lobehub/lobe-chat/discussions/6947)}. Regarding your issue with `TypeError: Cannot read properties of undefined (reading 'title')`, this error typically occurs when a component or page is trying to access a `title` property that is not defined. Here are some steps you can take to resolve this: 1. **Check for Undefined Props**: Ensure that all components and pages that rely on the `title` property have proper checks for undefined values. For example, in the `PageContent` component, the code uses a fallback to `result.originalUrl` if `title` is not defined ^{[[2]](https://github.com/lobehub/lobe-chat/blob/main/src/tools/web-browsing/Portal/PageContent/index.tsx)}. 2. **Conditional Checks**: Implement conditional checks for undefined props during prerendering. The `handlePayload` function in the `LobeMinimaxAI` configuration uses checks for undefined values ^{[[3]](https://github.com/lobehub/lobe-chat/blob/main/src/libs/agent-runtime/minimax/index.ts)}. 3. **Browser-Only APIs**: Verify that no browser-only APIs are being used during server-side rendering. The `idb-keyval` library is an example of a browser-only API that could cause issues if not properly checked ^{[[4]](https://github.com/lobehub/lobe-chat/blob/main/src/services/file/ClientS3/index.ts)}. 4. **File Structure**: Ensure that the file structure in the `pages/` directory is correct and does not contain non-page files that could lead to errors. 5. **Misconfiguration in `getStaticProps` or `getStaticPaths`**: Although I couldn't find specific information on these functions in the repository, ensure they are correctly configured to provide all necessary data for rendering. By addressing these areas, you should be able to resolve the TypeError related to undefined `title` properties during the build process. *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- ^{Help Dosu learn!

使用jenkins打包一直报很多TypeError: Cannot read properties of undefined (reading 'title')的问题 #7130
