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.

Object -> List`1
System.Object -> System.Collections.Generic.List`1[[TestA, TestProject.Application.Contracts, Version=0.1.0.0, Culture=neutral, PublicKeyToken=null]]

   at Volo.Abp.ObjectMapping.DefaultObjectMapper.AutoMap[TSource,TDestination](Object source)
   at Volo.Abp.ObjectMapping.DefaultObjectMapper.Map[TSource,TDestination](TSource source)

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

    Hi @maliming, thank you for your prompt reply.

    We dont have plan to upgrade the version yet, is there any workaround or any other solution to inject a service in AutoMapper?

    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.
