Boa noite.
Segui todos os passos do vídeo, assisti duas vezes para tentar descobrir onde errei no código, pois não está fazendo a transição. No console do navegador reporta erro na linha 4 do index.js: " index.js:4 Uncaught TypeError: Cannot read properties of null (reading 'addEventListener') at index.js:4:11".
Agradeço se alguém puder me ajudar.
Seguem abaixo meus códigos:
