Hello everybody, I am new in this community and finally it is this time when I have to ask you for your help. I would like to deploy my practice app in gh-pages. I read instructions how to do it and… it didn’t work. I still looking for a mistake I did but I can’t find it 😕

In dev tools console i received:
Failed to load resource: the server responded with a status of 404 ()
