Cannot find module '@as-integrations/express5' error in Fastify setup

[Gamote]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

We just upgraded to @nestjs/apollo@^13.2.0 so we can use the Apollo Server v5 introduced by the #3669.

But as soon as we do we get the following error

Error: Cannot find module '@as-integrations/express5'

We are using the Apollo Server with Fastify and not Express. Are we forced to install '@as-integrations/express5' although we already have @as-integrations/fastify@^3.0.0?

Related:

• Support Apollo Server v5 in Fastify integration apollographql/apollo-server#8142
• Add support for Apollo server v5 apollo-server-integrations/apollo-server-integration-fastify#308

If the issue is upstream, I think we should still address it in a way or another in the @nestjs/apollo as the 13.2.0 is a minor release but it breaks all Fastify setups.

Expected behavior

We expect that after upgrading to @nestjs/apollo@^13.2.0 from @nestjs/apollo@^13.1.0.

ℹ️ Currently we have fixed it by lazy-loading the @as-integrations/express5 when expressMiddleware is needed.
