Denis created
I created several modules using ABP suite. Every module provides API, does not have Web GUI. Also I have Application which generated by ABP Suite. I included my modules to application.
I run application and call endpoint of module. The endpoint returns OK result or ERR_INCOMPLETE_CHUNKED_ENCODING. But in the log I can find BusinessException expection which thrown during endpoint call. Also before this expection there is "An exception occurred, but response has already started" message.
The expection is thrown in local event handler, which is triggered in by domain entity.
When I run module separatly, using host in module solution, endpoint works well and returns error when exception occurs

hi @Denis
Can you share a project to reproduce this problem? @liming.ma@volosoft.com

Hi @maliming
Do you mean the project I currently working on? if yes, unfortunatly I can not But I could create sample project which repoduces this issue. I think it will be also easy for you
Steps
- Create module project
- Create entity with string Title property
- Add method SetTile which assigns Title on entity construction and fires local TitleCreated event
- Create TitleCreated event handler and make it throw excpetion
- Create application service with endpoint which creates Product in memory and saves it via repo. Create controller as well
- Create Application project
- Reference module in Application
- Run application and call endpoint

hi Denis
I am worried that I will miss some steps, can you directly send me a demo project that contains the above steps?

I would like to suggest remote session via TeamViewer or any other tool. I will show the issue. What do you think?

hi Denis
You have shared the steps to reproduce the problem, please share this project to me, it is very cumbersome to remotely check the source code.
