启动节点的内置Web服务器时出现ModelValidationException

我为节点的内置网络服务器定义了以下API：

@Path("example")
class ExampleApi(private val rpcOps: CordaRPCOps) {
    companion object {
        private val logger: Logger = loggerFor<ExampleApi>()
    }

    @GET
    @Path("test")
    fun test(@QueryParam("id") id: UniqueIdentifier) {

    }
}

当我启动节点的网络服务器时，出现以下错误：

您不能在节点内置网络服务器的API中使用UniqueIdentiifer作为端点参数类型。

您需要将标识符作为字符串传递，并使用UniqueIdentifier.fromString检索UniqueIdentifier。
