[Rails] whenever gem

I tried with these commands. It is fine. But the schedule.rb is not being
invoked.

I tried with some puts inside the method, but it is not getting invoked.

result of whenever -w -> [write] crontab file written

result of crontab -l :-
# Begin Whenever generated tasks for: the complete path/schedule.rb
