Bom... Sigo nesse problema a uma semana, não consigo resolver. Fiz todos os passos descritos no curso mas sempre da o mesmo erro. Baixei o arquivo "projeto-instalura-ssr" conforme é sugerido no curso, dou npm install e npm start e nada funciona. Com o percorrer desse curso tive muitos problemas de compatibilidade com versões desatualizadas no curso.
