Upsert fails silently

[slikts]

Working example: https://codesandbox.io/s/graphql-genie-upsert-issue-yckp9

• IDL
• Genie Version 0.4.24
• Fortune Adapter fortune-indexeddb 1.1.2

Schema:

type Item {
  id: ID!
  user: User!
  content: String!
}

type User {
  id: ID!
  name: String! @unique
  fullName: String!
  created: DateTime @createdTimestamp
}

Mutation:

mutation {
  createItem(
    input: {
      data: {
        user: {
          upsert: {
            create: { name: "test" }
            update: { fullName: "Test T." }
            where: { name: "test" }
          }
        }
        content: "Lorem ipsum"
      }
    }
  ) {
    data {
      id
      user {
        name
        fullName
      }
      content
    }
  }
}

The upsert fails silently and the user is not inserted.
