export async function createApolloClient(option: Option = {}) {

  const executableSchema2 = await getTransFormedRemoteExecutableSchema(uri2);

  const stitchedSchema = stitchSchemas({

대략 코드는 이런데 이게 런타임에 ApolloClient 를 셋업할때 실행되는 코드라서 codegen 으로 생성한 타입과는 달라지는게 문제입니다.. 따로 transform 만 진행하는 프록시 GraphQL api 를 파야할까요?
