File	Description
package.json	Updates @nestjs/platform-fastify dependency version to ^11.1.11
package-lock.json	Reflects the full dependency tree changes including major version upgrades for Fastify (3.x → 5.x) and numerous Fastify ecosystem packages, plus internal NestJS platform-fastify dependencies

⚠️ Critical Issues Found: This upgrade introduces breaking peer dependency mismatches that will prevent the application from running correctly. The upgraded package requires NestJS 11.x, but the project uses NestJS 7.x. This PR cannot be safely merged without also upgrading the entire NestJS ecosystem to version 11.

This upgrade introduces a critical peer dependency mismatch. The package @nestjs/platform-fastify@11.1.11 requires @nestjs/common@^11.0.0 and @nestjs/core@^11.0.0 as peer dependencies (as seen in lines 2105-2108 of package-lock.json), but the project is currently using @nestjs/common@^7.5.1 and @nestjs/core@^7.5.1.

This is a breaking change that will cause runtime errors. To safely apply this security upgrade, you need to also upgrade @nestjs/common, @nestjs/core, and likely other NestJS packages (@nestjs/graphql, @nestjs/microservices, etc.) to version 11.x. This is a major version upgrade across the entire NestJS ecosystem and will require significant testing and potential code changes to handle breaking changes between NestJS v7 and v11.

Suggested change

	"@nestjs/platform-fastify": "^11.1.11",
	"@nestjs/platform-fastify": "^7.6.15",

The upgraded @nestjs/platform-fastify@11.1.11 depends on fastify@5.6.2, which is a major version upgrade from the fastify@3.12.0 that was bundled with the old version. Fastify v5 has breaking changes from v3, including changes to plugin systems, lifecycle hooks, and TypeScript types. Additionally, apollo-server-fastify@^2.21.0 (line 32) may not be compatible with Fastify v5, as it was designed for Fastify v3. You should verify compatibility or consider upgrading to a newer Apollo Server version that supports Fastify v5.

Suggested change

	"@nestjs/platform-fastify": "^11.1.11",
	"@nestjs/platform-fastify": "^7.6.18",
