@witskeeper

BeforePublish is propagated based on the EntrySegmentContext created in BeforePublishStore. I saw that you judged _entrySegmentContextAccessor.Context == null in BeforePublish and created the EntrySegmentContext again. In fact, the Context here should not be null.

Have you configured SkyApm.Diagnostics.AspNetCore?

[witskeeper]

configure code like :

builder.Services.AddSkyAPM(ext => ext.AddAspNetCoreHosting().AddCap());

pulish code like：

 [HttpGet]
[Route("/sendEvent")]
public async Task SendEvent(OrderId id,[FromServices]ICarrierPropagator _carrierPropagator)
{
    await capPublisher.PublishAsync("OrderPaidIntegrationEvent", new OrderPaidIntegrationEvent(id), cancellationToken: HttpContext.RequestAborted);
}

BeforePublish dose not run under the async context in witch code calling PublishAsync,
it runs after the api function SendEvent return.
