Minimal reproduction of strange apollo provider bug with MockedProvider and array return types in newData

Steps to run after cloning this repo:

In two terminals:

cd workspaces/web && yarn && yarn start

To run tests with jest in workspaces, run

yarn test

cd workspaces/server && yarn build && yarn start #or yarn start:dev or nodemon

Web client runs on 3000 by default (is wrapped with CRA so will prompt if 3000 is occupied Server runs on 5000 by default, visit localhost:5000/graphql for playground

Sample server query:

query {
  getObjectWithArray {
    objectId
    objectList {
      subOjectId
      subObjectName
      subObjectDescription
    }
  }
}
