Ao criar APIs da web com FastAPI, se houver um erro em nosso código, o FastAPI normalmente o conterá na única solicitação que acionou o erro. 🛡

O cliente receberá um **Erro Interno do Servidor 500** para essa solicitação, mas o aplicativo continuará funcionando para as próximas solicitações em vez de travar completamente.
