ActiveRecord task executing in wrong environment with Whenever - ruby-on-rails

Question

I have to run a Cron task involving some data cleaning in my ActiveRecord database. I am using Whenever gem. Here is the code :
schedule.rb
every 1.hour do
rake 'notifications:clear'
end
notifications.rake
namespace :notifications do
task clear: :environment do
Rpush::Notification.delete_all
end
end
Running this gives me the following error:
rake aborted!
ActiveRecord::NoDatabaseError: FATAL: role "user_prod" does not exist
I am in development environment. Here is my database.yml file :
default: &default
adapter: postgresql
encoding: unicode
# For details on connection pooling, see Rails configuration guide
# http://guides.rubyonrails.org/configuring.html#database-pooling
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
development:
<<: *default
database: development_database
test:
<<: *default
database: test_database
staging:
<<: *default
database: staging_database
username: user_staging
password: <%= ENV['DATABASE_PASSWORD'] %>
production:
<<: *default
database: production_database
username: user_prod
password: <%= ENV['DATABASE_PASSWORD'] %>
Any ideas on why my ActiveRecord instruction seems to connect to my production environment ? Thanks in advance !

Update Your code with below :-
In schedule.rb file :-
every 1.hour do
rake 'notifications:clear', :environment => "development"
end
And finally executed this command :-
whenever --update-crontab
OR
Clear existing cron jobs.
crontab -r
Update cronjob with the environment.
whenever --update-crontab --set environment='development'
