Missing type map configuration or unsupported mapping #477

Here I need to use same ui page for both creating and editing where I have tried as shown below. But it gives error when do the mapping here : var property = input.Property.MapTo<Property>(); inside the "CreatePropertyAsync()" method. Could you tell me where is the issue ? All primary keys are int type.Is that the problem on here : public int? Id { get; set; } in the " PropertyEditDto " object ? B'cos I have given it null-bale hence we don't have a "Id" key for the Create property scenario. Edit scenario we do have value for that.If it is the problem how can I do this ? Any help would be highly appreciated. Thanks in advance.

Mapping error is : Message "Missing type map configuration or unsupported mapping.\r\n\r\nMapping types:\r\nPropertyEditDto -> Property\r\.IP.IpProperties.Dtos.PropertyEditDto -> .IP.IpProperties.Property\r\n\r\nDestination path:\r\nProperty\r\n\r\nSource value:\r\.IP.IpProperties.Dtos.PropertyEditDto"	string

                await UpdatePropertyAsync(input);
            }
            else
            {
                await CreatePropertyAsync(input);
            }
