Hi, I am trying to figure out how to inject a service in AutoMapper profile, I have tried the IMappingAction method from the link below: https://docs.automapper.org/en/stable/Before-and-after-map-actions.html
but got this exception:
[21:31:09 ERR] Error mapping types.

What did I miss in my configuration? Any help would be greatly appreciated.

Hi @maliming, the PR updated the AbpAutoMapperModule.cs, may I know how can I override this module file?
so far, I know how to override the application service/controller only: https://docs.abp.io/en/abp/4.4/Customizing-Application-Modules-Overriding-Services
Thank you.
