Cannot compile code

Hi,
I don't know what happened, several weeks i was compliing and running my code without any problem, but now suddenly compilation throws errors:

And when I run go get command without -u flag it throws the same error.

Any suggestion?

Thank you.

Outdated instructions to use this library

vgo has been superseded by go 1.11 and commands have changed slightly.

These instructions seem to work;

create a folder somewhere outside $GOPATH
go mod <your-module-name>
put a main.go file in there, importing github.com/TheThingsNetwork/go-app-sdk
go mod vendor
go run main.go

What I doubt still is whether this is the way it is supposed to work. go get github.com/TheThingsNetwork/go-app-sdk fails with type compatibility issue with lorawan package.

LastSeen is nil with deviceList

Hello

when requesting the devices as a list, the attribute LastSeen is nil. When using Get() to retrieve the device details it is correct.

Code (without error handling and defer):

client := config.NewClient(appID, appAccessKey)
devices, _ := client.ManageDevices()
deviceList, _ := devices.List(20, 0)
for _, dev := range deviceList {
	if dev.DevID == "b30fa2b5-edd3-4c4f-aa4e-a3c725016468" {
		fmt.Println(dev.AsDevice().LastSeen)
	}
}

dev, _ := devices.Get("b30fa2b5-edd3-4c4f-aa4e-a3c725016468")
fmt.Println(dev.LastSeen)

Output:

Installation errors

When running go get github.com/TheThingsNetwork/go-app-sdk I am getting the following error:

../../github.com/TheThingsNetwork/api/protocol/lorawan/message_conversion.go:57:26: cannot use cmd.MACCommand() (type lorawan.MACCommand) as type lorawan.Payload in append:

Any ideas?

Probably should not vendor types that are returned from functions/used in interfaces etc, as it makes it this package impossible to use as intended. If they must be vendored there should be a way for the user to create the type that wraps the vendored type without side effects.

So that people do not get errors like this:
cannot use u (type *"github.com/TheThingsNetwork/go-app-sdk/vendor/github.com/TheThingsNetwork/ttn/core/types".UplinkMessage) as type *"github.com/TheThingsNetwork/ttn/core/types".UplinkMessage)

same applies to other types vendored from ttn/core/types that are required to use this pkg: DeviceEvent, Activation, DownlinkMessage, NwkSKey, AppSKey, DevAddr,AppEUI and DevEUI.
