AutoMapper.AutoMapperMappingException: Error mapping types. #11717

alliance225 created 7 months ago

Hi, I have these entities: namespace DocuPro.DocumentBase { [Table("DocumentVersions")] [Audited] public class DocumentVersion : Entity, IMayHaveTenant { public int? TenantId { get; set; }

    public virtual int? DocumentId { get; set; }

    [ForeignKey("DocumentId")]
    public Document DocumentFk { get; set; }
    public virtual ICollection&lt;DocumentVersionFile&gt; DocumentVersionFiles { get; set; }


}

} namespace DocuPro.DocumentBase { [Table("DocumentVersionFiles")] [Audited] public class DocumentVersionFile : Entity, IMayHaveTenant { public int? TenantId { get; set; }

    public virtual string OCR { get; set; }

    public virtual string FileName { get; set; }
    
    
    public virtual int? DocumentVersionId { get; set; }

    [ForeignKey("DocumentVersionId")]
    public DocumentVersion DocumentVersionFk { get; set; }
    

    
    public virtual int? FileTypeId { get; set; }

    [ForeignKey("FileTypeId")]
    public FileType FileTypeFk { get; set; }

}

} namespace DocuPro.DocumentBase { [Table("FileTypes")] public class FileType : Entity {

    [Required]
    public virtual string Extension { get; set; }

}

}

I have this DTO: namespace DocuPro.DocumentBase.Dtos { public class GetDocumentVersionForViewDto { public DocumentVersionDto DocumentVersion { get; set; }

    public string DocumentLibelle { get; set; }

}

}

In my service I have this method:

public virtual async Task<List<GetDocumentVersionForViewDto>> GetAllDocumentVersion(int documentId) { // Fetching all DocumentVersions (and associated DocumentVersionFiles) for a specific documentId var documentVersions = await _documentVersionRepository.GetAllIncluding(dv => dv.DocumentVersionFiles) .Where(dv => dv.DocumentId == documentId) .ToListAsync();

  // Mapping to DTO
  var documentVersionDtos = ObjectMapper.Map&lt;List&lt;GetDocumentVersionForViewDto&gt;>(documentVersions);

  return documentVersionDtos;

}

I get this error: XHRGET https://localhost:44302/App/DocumentTabs/TabViewInfomations?documentId=8 [HTTP/2 500 Internal Server Error 250ms]
