Hi @anandwali,
I appreciate you bringing up this new issue :)

Could you kindly provide more details? I attempted to reproduce it, but everything seemed to be working perfectly fine.

I think the issue is Apollo Federation support was added back in 2020 for v1 of Federation and hasn't been updated since for v2.0 or newer

[oskargotte]

It seems you are right @cgriego. The code to handle federated schemas only considers v1 directives.
More directives needs to be included to support v2 and especially the @link directive which is present in all federated schemas using v2 or newer, see apollo.

@TuvalSimha Will you add support for federation v2? Is it in the pipeline? 😃

Opened up a PR for Apollo Federation V2 support: #2900

Will gladly discuss/make changes to get this merged
