使用Web服务器Spring Boot检索Corda IOU状态时出错

Question

当我尝试仅检索我的iou's State时，我以以下错误结束。这不仅是当我检索我的借条时，甚至当我执行常规查询以检索整个状态时，仍然会收到错误。似乎我需要使用Jackson进行配置，但是我不知道该怎么做。我将不胜感激！

这是我的API：

@GetMapping(value = ["my-ious"])
    fun getMyIOUs(): ResponseEntity<List<StateAndRef<IOUState>>> {
        val myious = proxy.vaultQueryBy<IOUState>().states.filter { it.state.data.lender.equals(proxy.nodeInfo().legalIdentities.first()) }
        return ResponseEntity.ok(myious)
    }

我在这里得到回应：
