我已经为节点的内置Web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Web服务器时，出现以下错误：

不能在节点内置 Web 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。
