si entra quindi nella nuova directory del template e si inserisce
ask deploy
ogni volta che e' stato modificato il codice in locale per effettuare l'upload della skill su Amazon si deve effettuare il deploy. Si puo' effettuare anche un deploy parziale della sola funzione Lambda con
ask lambda upload
Le Address API richiedono una autorizzazione esplicita da parte dell'utente per l'utilizzo. Si deve quindi andare su
https://alexa.amazon.it cliccare Le tue Skill, Skill attivate e cercare device-location-api-starter attivare la Skill con l'autorizzazione
a questo punto si e' presentato un problema. La skill era priva di endpoint perche' non e' stata creata la corrispondente funziona Lambda. Ho quindi proceduto a creare una Lambda copiandoci poi sopra il file index.js che ho trovato nel template
