Receiving error when attempting to verify a virtual machine order - go

Question

When I run the below code I get the error SoftLayer_Exception_InvalidValue: Invalid value provided for 'blockDevices.device'. A device number must be provided for all block devices. (HTTP 200)
What is wrong with the way I initialize the block devices?
I see the fields, Id and Uuid for type Virtual_Disk_Image, but no number. From the descriptions it sounds like these values are set post-creation.

sess := session.New(*c.user, *c.key)
service := services.GetVirtualGuestService(sess)
guestTpl := getGuestTplTest()
guest, err := service.GenerateOrderTemplate(&guestTpl)
if err != nil {
return "", err
}
productOrderInstance := services.GetProductOrderService(sess)
_, err = productOrderInstance.VerifyOrder(guest)
if err != nil {
return "", err
}
return "success", nil

You just need to add the attribute ¨Device¨ for each Virtual_Guest_Block_Device object and the ¨ LocalDiskFlag ¨ attribute must be added once and not for each Virtual_Guest_Block_Device.
The same that this example:
blockDevices := make([]datatypes.Virtual_Guest_Block_Device, 2)
blockDevices[0] = datatypes.Virtual_Guest_Block_Device{
Device: sl.String("0"),
DiskImage: &datatypes.Virtual_Disk_Image{
Capacity: sl.Int(100),
},
}
blockDevices[1] = datatypes.Virtual_Guest_Block_Device{
Device: sl.String("2"),
DiskImage: &datatypes.Virtual_Disk_Image{
Capacity: sl.Int(100),
},
}
After that you have to add the symbol ¨&¨ to the parameter ¨ guest ¨ in the method
VerifyOrder without this the code will not run.
result, err := productOrderInstance.VerifyOrder(&guest)
