Plugin schema-ast and typescript not found when using Yarn 3 workspaces

[Poolshark]

Hey! I'm using code-gen for a while and up to now everything was working fine. I recently ported my monorepo to Yarn 3 and this is where the problems started. To be clear, everything works aas long as I don't use workspaces but when using workspaces it seems like that (certain) plugins are not getting found.

The following works:

// folder structure in repo

tools/
  scripts/
    code-gen/
      src/
        script.ts

tsconfig.json
package.json

The tsconfig.json is

{
  "compilerOptions": {
    "target": "ES2017",
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,
    "skipLibCheck": true,
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "noFallthroughCasesInSwitch": true,
    "module": "esnext",
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": false,
    "types": ["node", "jest"]
  }
}

The package.json (the necessary dependencies) is

"devDependencies": {
    "@graphql-codegen/cli": "^2.6.2",
    "@graphql-codegen/schema-ast": "^2.4.1",
    "@graphql-codegen/typescript": "^2.4.7"
}

and in my script.ts I generate a schema from a remote endpoint with

await generate(
      {
        silent: true,
        errorsOnly: true,
        overwrite: true,
        generates: {
          [`${process.env.CLIENT_SCHEMA}.graphql`]: {
            schema: {
              [`${endpoint}/graphql`]: {
                headers: {
                  "Dg-Auth": adminApiKey,
                },
              },
            },
            plugins: ["schema-ast"],
          },
          [`${process.env.CLIENT_SCHEMA}.ts`]: {
            schema: `${process.env.CLIENT_SCHEMA}.graphql`,
            plugins: ["typescript"],
          },
          [`${process.env.ADMIN_SCHEMA}.ts`]: {
            schema: `${process.env.ADMIN_SCHEMA}.graphql`,
            plugins: ["typescript"],
          },
        },
      },
      true
    );

Like I've said, this all works perfectly but as soon as I transfer this into a Yarn workspace, where scripts is a package, I get the error

Invalid Custom Plugin "typescript" for "config/schemas/admin/schema.ts"
        Plugin typescript does not export a valid JS object with "plugin" function.

        Make sure your custom plugin is written in the following form:

        module.exports = {
          plugin: (schema, documents, config) => {
            return 'my-custom-plugin-content';
          },
        };
        

Unable to find template plugin matching schema-ast for "config/schemas/client/schema.graphql"
        Unable to find template plugin matching 'schema-ast'
        Install one of the following packages:

        - @graphql-codegen/schema-ast-plugin
        - graphql-codegen-schema-ast
        - graphql-codegen-schema-ast-template
        - graphql-codegen-schema-ast-plugin
        - codegen-schema-ast
        - codegen-schema-ast-template
        - schema-ast

Did anyone experience the same issue or knows what's going on here?

Thanks!

Thanks! I have done so here. I hope this was intended to be a bug report.

Let me know if there is anything I should do differently!
