NestJS docs:

@nestjs/graphql@>=9 and @nestjs/apollo^10 packages are compatible with Apollo v3

Apollo docs:

Apollo Server 3 supports Fastify v3.

nestjs/platform-fastify@9.0.4 dependency:

   "@fastify/cors" "8.0.0"
    "@fastify/formbody" "7.0.1"
    "@fastify/middie" "8.0.0"
    fastify "4.2.1"
    light-my-request "5.1.0"
    path-to-regexp "3.2.0"

@fastify/cors and @fastify/formbody supports Fastify versions 3.x

Fastify v4 cannot be used with apollo-server-fastify v3. If you're using Fastify + NestJS + Apollo, I'd suggest not upgrading to v9 just yet
