To fix this!

use batch: true even to your main and subschemas (this will give you back aliases but not the one passed from the client)

$ git clone [email protected]:Rowadz/potential-schema-stitching-bug.git
$ cd potential-schema-stitching-bug
$ npm i
# I'm using node 18
$ npm run dev

When running the following query I would suspect that the info.path.key property in each resolver to be userAlias01 and userAlias02 but it's not, it's only user

This only happens in the first level resolvers

query users {
  userAlias01: user(id: 1) {
    id
    name
  }
  userAlias02: user(id: 2) {
    id
    name
  }
}
