How to handle when query depends on a non string/JSON serializable object reference?

class ObjectHasher {
  static referenceToHash = new WeakMap()

  static getHash(obj: any) {
    const found = this.referenceToHash.get(obj)
    if (found) return found

    const hash = randomString()
    this.referenceToHash.set(obj, hash)
    return hash
  }

  static getReference(hash: string) {
    return this.referenceToHash.get(hash)
  }
}

function App() {
  const {} = useQuery({
    queryKey: [userId, ObjectHasher.getHash(largeObject)] as const, // <-- this turns into a string
    queryFn: ctx => {
      const [userId, hash] = ctx.queryKey
      const reference = ObjectHasher.getReference(hash) // <-- then I get it back later

      ...
    },
  })
}
