Я новичок в .NET 6 и пытаюсь настроить базовый API, который будет хранить коллекционные карточки в базе данных в качестве практики.
Однако при попытке протестировать запрос POST Я получаю сообщение об ошибке автосопоставления.
An unhandled exception has occurred while executing the request.
AutoMapper.AutoMapperMappingException: Missing type map configuration or unsupported mapping.
Это моя программа.cs. Ошибка находится в следующей строке:
