If test contains await, then [AllureStep] failed with System.ArgumentNullException : Value cannot be null. (Parameter 'key')

[redfirefox]

This code given exception:
[Test]
public async Task Test()
{
await Task.Delay(1000);
Hello();
}

[AllureStep]
public void Hello()
{
}

System.ArgumentNullException : Value cannot be null. (Parameter 'key')
Stack Trace:
ConcurrentDictionary2.ThrowKeyNullException() ConcurrentDictionary2.TryGetValue(TKey key, TValue& value)
ConcurrentDictionary2.get_Item(TKey key) AllureStorage.Get[T](String uuid) AllureStorage.AddStep(String parentUuid, String uuid, StepResult stepResult) AllureLifecycle.StartStep(String parentUuid, String uuid, StepResult stepResult) AllureLifecycle.StartStep(String uuid, StepResult result) AllureStepAspect.WrapStep(String name, MethodBase methodBase, Object[] arguments, Func2 method)
Tests.__a$_around_Hello_100663386_w_0(Object[] )
Tests.Hello()

But this code - successful:
[Test]
public async Task Test()
{
Task.Delay(1000).GetAwaiter().GetResult();
Hello();
}

I reproduced this issue, debugged through allure.commons.
But can't answer why with await new step we create can't find its parent.

I have this issue too. Very perplexing.

please follow https://github.com/allure-framework/allure-csharp/tree/main/Allure.NUnit
since all the code there - should be much easier to fix
