I’m getting the following error:
Referência de objeto não definida para uma instância de um objeto.
The line generating the error is as follows:
var _TceView = MapperFacade.MapperConfiguration.Map<TceView>(await _TceRepositorio.buscarTce(pIdTce));
What’s the problem? I’ve fucked up the whole code and I can’t find it.

Check the return of the method _TceRepositorio.buscarTce(pIdTce). It must be returning a null value. Below is an approach that facilitates its verification:
var testObject = await _TceRepositorio.buscarTce(pIdTce);
// Coloque um breakpoint neste ponto e verifique se o testObject está nulo,
// isto deve estar causando o seu erro, caso esteja chegando um valor nulo,
// implemente verificações no código para tratar situações como esta.
var _TceView = MapperFacade.MapperConfiguration.Map<TceView>(testObject);
Better validate your business rule to identify if the object returned by the method buscarTce() may or may not work with null values.
I did this but it is bringing the object yes, I keep getting the same error when it reaches the line: var _Tceview = Mapperfacade.MapperConfiguration.Map<Tceview>(testObject);
@Joãoignácio, then what may be happening is some property of the Tceview object that is coming null and the class does not accept null.
What happened was that at the start of the application the automapper class was not being instantiated so the mapping was not happening, I made the change and the application ran normally.

Referência de objeto não definida para uma instância de um objetooccurs when you try to do something on an objectnulo. Looking at your code I believe that the_TceRepositorio.buscarTce(pIdTce)is not returned a record, and theMapperFacade.MapperConfiguration.Map<TceView>while trying to makeTceView.Campogives the error in question.– Tiedt Tech
