This major version upgrade from ^12.0.5 to ^15.5.10 will introduce significant breaking changes and is highly likely to break the application. The Snyk report itself flags this as a breaking change.

Key issues include:

  1. React Version Incompatibility: Next.js v13 and later versions require React 18. This project currently uses React 17. The build will fail without upgrading react and react-dom and adapting the code to React 18's new features, like the root API.

  2. Deprecated next.config.js Options: Your next.config.js uses options like target: 'experimental-serverless-trace' and the future.webpack5 flag, which are deprecated or removed in newer Next.js versions. These will need to be updated to their modern equivalents (e.g., the output option).

  3. Suspicious Target Version: The target version 15.5.10 is questionable, as the latest stable Next.js version is v14.x. The vulnerability this PR aims to fix (SNYK-JS-NEXT-15104645) is patched in version 14.1.1.

Due to these issues, a direct merge is not feasible. A manual migration, carefully addressing the breaking changes between major Next.js versions (12 -> 13 -> 14), is required.
