Answer 1

first you should add this command npx apollo service:download --endpoint= schema.json

then run this command npx apollo codegen:generate --localSchemaFile=graphql-schema.json --target=typescript --tagName=gql

Answer 2

I think you need to check schema.json file inside your project, i have also faced same issue and same error but solved by adding schema.json file inside project directory

You can download it by below command

apollo schema:download --endpoint=http://localhost:8080/graphql schema.json
