I'm creating simple test recipe with a template and data bag. What I'm trying to do is creating a config file from data bag that has simple nested information, but I receive error "can't convert String into Integer"

Here are my setting file

1) recipe/default.rb

data1 = data_bag_item( 'mytest', 'qa' )['test']
data2 = data_bag_item( 'mytest', 'qa' )
template "/opt/env/test.cfg" do
source "test.erb"
action :create_if_missing
mode 0664
owner "root"
group "root"
variables({
:pepe1 => data1['part.name'],
:pepe2 => data2['transport.tcp.ip2']
})
end

2)my data bag named "mytest"

$knife data bag show mytest qa

id: qa
test:
part.name: L12
transport.tcp.ip: 111.111.111.111
transport.tcp.port: 9199
transport.tcp.ip2: 222.222.222.222

3)template file test.erb

part.name=<%= @pepe1 %>

transport.tcp.binding=<%= @pepe2 %>

Error reurns when I run chef-client on my server,

/var/chef/cache/cookbooks/config_test/recipes/default.rb:

17: group "root"
18: variables({
19>> :pepe1 => data1['part.name'],
20: :pepe2 => data2['transport.tcp.ip2']
21: })
22: end 23:

I tried many things and if I comment out "pepe1 => data1['part.name'],", then :pepe2 => data2['transport.tcp.ip2'] works fine. only nested data "part.name" cannot be set to @pepe1.

Does anyone knows why I receive the errors?

thanks,
