typescript - GraphQL mutation for 2 entities with parent-child relation returns old value for second entity

Question

I'm using apollo server.

While mutating data I need to update 2 tables: location and address.

End of resolver function:

const locationUpdated = await db.location.updateLocation(user.id, location);
const addressUpdated = await db.address.updateAddress(user.id, location.address);
return { error: null, location: { ...locationUpdated, address: addressUpdated } };

Using GraphQL Playground:

mutation {
  updateLocation(
    location: {
      id: 1
      label: "label12"
      address: { 
        city: "city12"
      }
    }
  ) {
    error
    location {
      label
      address {
        city
      }
    }
  }
}

As a result I have new location.label but old location.address.city:

{
  "data": {
    "updateLocation": {
      "error": null,
      "location": {
        "label": "label12",
        "address": {
          "city": "city11",
        }
      }
    }
  }
}

Database is updated correctly. Looks like server uses cache?

You can try the following two ways

1. override the server caching setting. Ref

const server = new ApolloServer({
  // ...
  cacheControl: {
    defaultMaxAge: 0,
  },
}));

type Post @cacheControl(maxAge: 240) {
  id: Int!
  title: String
  author: Author
  votes: Int @cacheControl(maxAge: 30)
  comments: [Comment]
  readByCurrentUser: Boolean! @cacheControl(scope: PRIVATE)
}

type Comment @cacheControl(maxAge: 1000) {
  post: Post!
}

2. updating the id. Ref

updateLocation(
    location: {
      id  //from the doc, I saw that the id must be updated as well, you can try take out the hard code `1`
      label: "label12"
      address: { 
        city: "city12"
      }
    }
  )
