Mongodb replication

I have mongodb replication script which is not working, getting error. Any idea how to make it work. Appreciate any kind of help. I am trying this on Opsworks Chef 12 but this works fine on Chef 11

instance = search("aws_opsworks_instance", "self:true").first
stack = search("aws_opsworks_stack").first

script 'initiate_replset' do
  subscribes :run, 'service[mongod]'
  interpreter "ruby""Running replset initiate script")
  code <<-EOH
	require 'json'
    retries = 0
    until JSON.parse('mongo localhost:27017 --quiet --eval "JSON.stringify(rs.status())"')['ok'] == 1 || retries == 40
	# Make this more readable
	'mongo localhost:27017 --quiet --eval "JSON.stringify(db.adminCommand({"replSetInitiate" : {_id: "#{stack['name']}", members: [{_id: 1, host: "mongodb1.#{stack['name']}.#{node['domain_name']}:27017"},{_id: 2, host: "mongodb1.#{stack['name']}.#{node['domain_name']}:27017"},{_id: 3, host: "mongodb1.#{stack['name']}.#{node['domain_name']}:27017"}]}}))"'
	retries += 1
  action :nothing

Consider mongodb-lib cookbook if you are planning to go with 12+ Chef.
