Hi Matthias,

After removing the square blacked, everything went well.

Thank you so much.

Hi,

you should remove the square brackets from your data bag. It should look like 
this:

> {
> "test": {
>  "part.name": "L12",
>  "transport.tcp.ip": "111.111.111.111",
>  "transport.tcp.port": "9199"
> },
> "transport.tcp.ip2": "222.222.222.222",
> "id": "qa"
> }

alternatively, you need to access the part.name by first accessing the 
array's first element:
> data1 = data_bag_item( 'mytest', 'qa' )['test'].first
or, similar
> data1 = data_bag_item( 'mytest', 'qa' )['test'][0]

If you want to nicely nest your data bag, this could be what you initially 
tried to do? But I'm guessing:
> {
> "test": {
>  "part": {
>    "name":  "L12",
>    "transport": {
>      "tcp": {
>        "ip": "111.111.111.111",
>        "port": "9199"
>      }
>    }
>  }
> },
> "transport": {
>  "tcp": {
>    "ip2": "222.222.222.222"
>  }
> },
> "id": "qa"
> }

hope this helps,
Matthias
