      action: "transfer",
      name: "Donazione",
      receiver:"01F3MHQ0KWJC7M19B1E8BXVY46",
      resourceInventoriedAs:"01FFPTBZ2HGX9KQT7KRRQBKA5J"
      availableQuantity: {hasUnit: "01FFJEBJ4S4E4ZDWZNEWYFZYD7", hasNumericalValue: 10}
      due: "2021-09-20T14:10:20+01:00"
  }
  ) {
    intent {
      id
      name
      due
    }
  }
}

results in

{
  "data": {
    "createOffer": {
      "intent": {
        "due": null,

      }
    }
