2. My GraphQL operations:
   happens with any operations

3. My codegen.yml config file:

overwrite: true
schema: "http://localhost:4000"
documents: "**/*.graphql"
generates:
  src/generated/graphql.ts:
    plugins:
      - "typescript-react-apollo"
  ./graphql.schema.json:
    plugins:
      - "introspection"

Expected behavior
Successful script run.

Environment:

• OS:
• @graphql-codegen/...:
• NodeJS: tried v12 and v10

Have the same problem with v1.2.1, but v1.2.0 works

You are trying to parse a Typescript module definition as a GraphQL document.

Are you sure you really want to parse all .graphql files in node_modules? If not, you can either specify your .graphql files explicitly, put them in a subfolder and parse only that folder, or exclude node_modules with:

documents: "{,!(node_modules)/**/}*.graphql"

@pnordhus Thanks, that works (seeing a different error now though). This yml was given to me by the init function so I expected sensible defaults in an empty CRA app... 🤔

Same here—encountered the same issue also using a file generated by the wizard. Error didn’t make it clear it was a misconfiguration on my part

[dotansimha]

The init suggests to use **/*.graphql, but the default should be src/**/*.graphql to avoid including node_modules as default.
Updated it in: https://github.com/dotansimha/graphql-code-generator/pull/2012

Fixed in 1.3.0 🎉
