Olá pessoal,
Fiz meu projeto assim como explicado no vídeo e no texto, mas quando digito o usuário e a senha dá o seguinte erro: HTTP Status 500 - net.vidageek.mirror.exception.ReflectionProviderException: Could not invoke method autentica.
Já pesquisei aqui na alura e na internet e até agora não consegui resolver.
Segue o erro mais detalhado:
