Fix TurbopackInternalError

in Next.js

Solution

TurbopackInternalError generally arises from problems with file system access, particularly issues with symlinks, incorrect paths, or restricted permissions during the build process. Ensure your project's file paths, including outputFileTracingRoot, are valid and accessible, and that symlinks within your `node_modules` or project directory are correctly resolved and do not point outside of the project root; consider using the `realpath` command to normalize paths. If using Windows, verify adequate permissions for file operations and consider disabling developer mode or enabling long path support if symlink creation faces issues.
