Boa Noite

Dá uma olhada se você configurou certinho lá no netlifly o build comand usando o yarn, pelo que parece ele não tá conseguindo dar build no seu projeto.

Oi Rafael boa noite obrigado por responder a minha dúvida! Sim eu configurei de acordo com o que é mostrado no vídeo vídeo do professor Nélio, já tentei 10x, não sei se mudou alguma coisa! Em fim! Obter o Outlook para Android<https://aka.ms/AAb9ysg>
