Inizia con le chiamate a GenerateContent e i file di riproduzione nel repository Issue-OpenHandle-VertexAI-NodeJs collegato, quindi esegui i test con il prompt di grandi dimensioni. Confronta l’esecuzione con il prompt di grandi dimensioni con i due test superati e traccia quale handle rimane aperto. Il lavoro è completato quando il test pertinente termina senza un handle aperto.
