go - Unable to get itemCategory info from call GetConfiguration when called from golang

Question

The api call

GET https://api.softlayer.com/rest/v3/SoftLayer_Product_Package/257/getConfiguration?objectMask=mask[itemCategory]

returns an object, []datatypes.Product_Package_Order_Configuration where ItemCategory is populated. sample output:

{
"id": 7167,
"isRequired": 0,
"itemCategoryId": 390,
"orderStepId": 1,
"packageId": 257,
"sort": 0,
"itemCategory": {
"categoryCode": "trusted_platform_module",
"id": 390,
"name": "Server Security",
"quantityLimit": 1,
"sortOrder": 0
}
},

When I attempt the same call in go, itemCategory is not populated, even though I declare it in the mask. Please advise.

package main

import (
"fmt"
"github.com/softlayer/softlayer-go/services"
"github.com/softlayer/softlayer-go/session"
"encoding/json"
)

func main() {
    // SoftLayer API username and key
    username := "set-me"
    apikey   := "set-me"

    // Create a session
    sess := session.New(username, apikey)

    // Enable debug
    sess.Debug = true

    // Get SoftLayer_Account service
    service := services.GetProductPackageService(sess)

    // Object-Mask to get specific Vlan's information
    mask := "itemCategory"

    // Call to getNetworkVlans in order to retrieve vlans according to filter.
    result, err := service.Mask(mask).Id(257).GetConfiguration()
    if err != nil {
        fmt.Printf("
 Unable to retrieve config:
 - %s
", err)
        return
    }

    // Following helps to print the result in json format.
    jsonFormat, jsonErr := json.MarshalIndent(result,"","     ")
    if jsonErr != nil {
        fmt.Println(jsonErr)
        return
    }
    fmt.Println(string(jsonFormat))
}

sample output:
