Disable Caching for Apollo Server

Question

My Apollo Server's resolver has a different return value than the response. I assume that the problem is caching. The E-Tag stays the same since 2 hours, I guess. I have an apollo Server and an apollo client via react.

What I have tried

Client

• How to disable cache in apollo-link or apollo-client?
• Playing with Chrome's features, like What's the difference between "Normal Reload", "Hard Reload", and "Empty Cache and Hard Reload" in Chrome? and
• Chrome - "disable cache"

Server

Server-side caching:

Query resolver

async getXY(_, { _id }: IGetXY, context, info: GraphQLResolveInfo) {
      info.cacheControl.cacheHint = { maxAge: 0, scope: CacheScope.Private }
[...]
return {...}
}

Behaviour

{
  "question": "60db0a6cc405dd2eb4d1f1dc",
  "Answer": {
    "valBool": false,
    "valString": null,
    "__typename": "Answer"
  },
  "__typename": "Items"
}

Expected

{
  "question": "60db0a6cc405dd2eb4d1f1dc",
  "Answer": {
    "valBool": false,
    "valString": null
  }
}

Expected
