The application failed to start. Contact the author for more information but i don't have error logs in shiny

I just deploy my first app on the shinyapps.io, everything fine with that.
The problem is that the message “The application failed to start. Contact the author for more information” appears if I try to enter to the page.
The logs seem to be fine too, this is the last log:

I think that I don't have errors in the log and I don't know what's happening.
