Following is my codegen.yml

schema: "http://localhost:4040/graphql"
documents: "src/graphql/**/*.ts"
generates:
  src/generated/graphql.tsx:
    plugins:
      - "typescript"
      - "typescript-operations"
      - "typescript-type-graphql"
      - "introspection"
      - "typescript-react-apollo"
    config:
      withHooks: true
      withHOC: false

Any help is much appreciated.

Hi @palaparthi !
It seems like your server responds to your request, but returns 404 for your endpoint. It's probably something related to your server.

If this is still relevant, please report an issue in this repo, with a complete reproduction.
