find(:all) method is deprecated in Red Hat Cloudforms 4.2

Issue

• Below automate code works in Red Hat Cloudforms 3.2 but not in Red Hat Cloudforms 4.2:

$evm.vmdb('cloud_tenant').find(:all).each do |project|
  #if vm.evm_owner_name == myname && vm.vendor == 'OpenStack' && vm.active
  # $evm.log("info", "sam project>>>  \t : #{project.inspect}")
  project_name=project[:name]
  project_id=project[:id]
  if project_name.eql?(alloc_tenant_project)
    $evm.log("info", "sam alloc_tenant_project Found !!!!!! ID cis: "+project_id.to_s)
    prov.set_option(:cloud_tenant,[project_id,project_name])
    found=true
  end
end

Line 1 ($evm.vmdb('cloud_tenant').find(:all).each do |project|) encountered error and here is the error log:
