在Corda流测试中获取节点标识信息时出现Quasar异常

我有使用（测试）密钥管理服务执行流逻辑以生成新参与方和证书的流测试。在安装时，我创建了一个模拟网络实例以及多个

StartedMockNode

实例。我们的项目是用Kotlin1.1.60编写的，使用corda-3.3开源（OS），运行在JDK1.8_192上。在IntelliJ Idea 2019.3中运行测试时，我从quasar库中得到以下异常

我的代码在流程或测试逻辑上与corda文档中推荐的方法没有任何明显的偏差。有关如何解决此问题的任何想法？

切换IntelliJ设置似乎可以解决此问题。在“Preferences”->“Build，Execution，Deployment”->“Gradle”->“Build and run using”到“Gradle”而不是“IntelliJ Idea”中更新测试设置，并且在“run tests using”到“Gradle”而不是“IntelliJ Idea”的正下方，流测试按预期成功运行。无需进行其他更改
