Mask and filter are not working when using the Sof

Question

When I add billingItemFlag to my mask and filter it is missing in the results. I am using the SoftLayer-go api from the SoftLayer GitHub account. Is my filter or mask wrong?

Please consider the following code:

const mask string = "id;hostname;domain;billingItemFlag;billingItem"
var filters = filter.Build(
    filter.Path("billingItemFlag").NotNull(),
    filter.Path("billingItem").NotNull(),
)
accountService := services.GetAccountService(softlayerSession)
hardware, err := accountService.Filter(filters).Mask(mask).Limit(1).GetHardware()
if err != nil {
    panic(err)
}
println(hardware[0].BillingItemFlag)

The result of this code is "0x0" which is an invalid memory address.

When I enable debugging I can see the fields are not being returned but domain, hostname, and others are.

The code you posted works when using the default endpoint or any other REST endpoint. It seems an issue from API, I recommend to switch to the default endpoint or use:
