- Repro Steps:
- Created a new solution (Acme.BookStore) with ABP CLI
- Generated CRUD entity (Book) and pages with ABP Suite
- Created a LocalEventHandler to handle EntityCreatedEventData for the generated entity that throws a UserFriendlyException
- Doing POST /api/app/books via swagger results in a response with with an undocumented code and details stating "Error: response status is 200":
- Creating an entity from the generated create modal displays a dialog stating "An error has occurred! Error detail not sent by server":
- We would like both of these scenarios to display a more appropriate response, any help would be greatly appreciated
Thanks in advance

hi
Doing POST /api/app/books via swagger results in a response with with an undocumented code and details stating "Error: response status is 200":
When ILocalEventHandler throws an exception, the HTTP response has already been written. We cannot change it anymore.
Creating an entity from the generated create modal displays a dialog stating "An error has occurred! Error detail not sent by server"
handles an exception that returns an object result (not a view result).
public async Task<NoContentResult> OnPostAsync() { await _booksAppService.CreateAsync(Book); return NoContent(); }Markdown supported.Copy, paste, or drag & drop images and files (max 100 MB per file, 100 MB total per post)
