I am using below env:

Ruby -> 3.0.0p0
Rails -> 6.1.6
Crono -> 2.0.0

I am getting below error while running the Test job mentioned in its document:

I, [2022-07-01T20:34:39.036394 #4638] INFO -- : Perform Test
E, [2022-07-01T20:34:39.037945 #4638] ERROR -- : Finished Test in 0.00 seconds with error: wrong number of arguments (given 1, expected 0)

The job I have defined in crontab as per its doc
`
require 'rake'

Rails.app_class.load_tasks

class Test
def perform
Rake::Task['crono:hello'].execute
end
end

Crono.perform(Test).every 5.seconds`

I have aslo define the rake task in lib/tasks/test.rake as needed
namespace :crono do desc 'Update all tables' task :hello => :environment do puts "hello" end end

Do we have any way to fix this?
My application heavily based on job scheduling and this issue of crono with Ruby 3.0 preventing me from upgrading my app to Ruby 3
