当我到达终点时，@Karate Gatling 没有生成报告

Question

我的加特林机模拟 class,

class <MyClass> extends Simulation {
  before {
    println("Simulation is about to start!")
  }
  val smapleTest = scenario("test").exec(karateFeature("classpath:demo/get-user.feature"))
  setUp(
    smapleTest.inject(rampUsers(1) over (10 seconds))).maxDuration(1 minutes)
  //).assertions(global.responseTime.mean.lt(35))
  after {
    println("Simulation is finished!")
  }
}

我得到-user.feature文件，

Scenario Outline: Hit wskadmin url
    Given http://172.17.0.1:5984/whisk_local_subjects/guest 
    And header Authorization = AdminAuth
    And header Content-Type = 'application/json'
    When method get
    Then status <stat>
    * print result
    Examples:
      | stat |
      | 200  |

当我运行模拟 class 时，在控制台日志下方我得到：

Simulation com.karate.openwhisk.performance.SmokePerformanceTest started...

注意：这里我在 34 mili 秒内得到响应，但门控无法生成报告。以下是我收到的错误消息

错误：

但是如果我运行相同的模拟文件在特征文件中简单的改变如下

Scenario Outline: Hit wskadmin url
        Given http://172.17.0.1:5984/whisk_local_subjects/guest 
        And header Authorization = AdminAuth
        And header Content-Type = 'application/json'
        When method get
        Then status <stat>
        * print result
        Examples:
          | stat |
          | 200  |
          | 200  |

然后 gatling 生成报告。请帮我看看根本原因是什么。

感谢您对空手道格林的兴趣和非常详细的报告。

这个 is a bug，我们已经修复并刚刚发布了它。

你能把你的 karate-gatling 版本升级到 0.8.0.1 并告诉我进展如何吗？
