Modern Front-End Development for Rails: B7 running the example app fails( page xv)

Page xv invites us to run the example app with rails s. I get this error:
Showing <APP_DIR>/turbo/01/app/views/concerts/_schedule_concert.html.erb where line #37 raised:

undefined method `favorite' for nil:NilClass

It seems current_user is undefined.

Marked As Solved
