Automapper missing type map configuration or unsupported mapping – Error

by

Where have you specified the mapping code (CreateMap)? Reference: Where do I configure AutoMapper?

If you’re using the static Mapper method, configuration should only happen once per AppDomain. That means the best place to put the configuration code is in application startup, such as the Global.asax file for ASP.NET applications.

If the configuration isn’t registered before calling the Map method, you will receive Missing type map configuration or unsupported mapping.
