It might help if you can share the contents of your `apollo-codegen-config.json` file. That error sounds like there is duplication of the schema in more than one file.

Some suggestions:

- make sure that countrylist.graphql is only you operations
- make sure that schema.graphqls is only the schema

What is `countryListAPI.json`?
