Describe the bug

After migrating from yarn, to yarn 4 with workspaces, the codegen does not work anymore:

✔ Parse Configuration
⚠ Generate outputs
  ❯ Generate to src/queries/generatedGQLTypes.ts
    ✔ Load GraphQL schemas
    ✔ Load GraphQL documents
    ✖ Cannot use GraphQLNonNull "join__Graph!" from another module or realm.
      Ensure that there is only one instance of "graphql" in the node_modules
      directory. If different versions of "graphql" are the dependencies of oth…
      relied on modules, use "resolutions" to ensure only one version is instal…
      https://yarnpkg.com/en/docs/selective-version-resolutions
      Duplicate "graphql" modules cannot be used at the same time since differe…
      versions may have different capabilities and behavior. The data from one
      version used in the function from another could produce confusing and
      spurious results.

Steps to Reproduce the Bug or Issue

Expected behavior

I'd expect codegen to be ok with the available graphql package

Additional context

I will try to create a sandbox later

can you try yarn resolutions and force only 1 package of graphql?

[platzhersh]

I have already added a resolutions:

    "resolutions": {
        "graphql": "16.8.1"
    },

it didn't help unfortunately

[saihaj]

Can you please share a minimal reproduction. You can either use StackBlitz, CodeSandbox or a public GitHub repo.

[platzhersh]

Thank you for insisting, I just did that, could not reproduce it.

Realised that I had some stale node_modules in my sub-workspaces that were causing the issue.

No bug therefore, just a clumsy dev - me :-)
