VertexByID() error

[Ara Israelyan]

There is an error when calling VertexByID()

client, err := grammes.DialWithWebSocket(addr)
if err != nil {
	log.Fatal(err)
}
defer client.Close()

verts, err := client.AllVertices()
if err != nil {
	log.Fatal(err)
}

for _, vert := range verts {
	v, err := client.VertexByID(vert.ID())
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(v.ID())
}

Output error:
