apollo-server-express fails to resolve graphql 16 using yarn PnP

[evanrlong]

I am trying to use apollo-server-express in a project using yarn 3 w/ PlugNPlay dependency resolution. When I run yarn add apollo-server-express inside my project, I expect it to include the package without errors. Instead, I see this...

And running yarn explain peer-requirements <hash> yields...

The problematic area seems to be an incorrect peerDependency inside @apollographql/apollo-tools@0.5.2. Strangely, that package does not seem to have any listed peerDependencies, so I'm a bit stumped.

Here is a minimal reproduction...

Could someone please take a look so that we can use graphql@16.x and apollo-server-express within yarn projects? Thanks!

Yarn hardcodes the peer dependency because graphql-tools forgot to do it; a PR is open here but it hasn't been merged yet.

thanks. apollo-tooling has been deprecated for a while and we are working to remove the vestigial uses of it in Apollo Server as part of our AS4 work. but we should probably fix the apollo-tools peer dep for now, since it is a dependency of AS even if it's only used by one particular modules option.
