Vertex API (gemini-pro model) undefined method `has_key?' for ...

Riproduci la richiesta con l'esempio gemini-pro e traccia la decodifica da stream_project_location_publisher_model_generate_content in service.rb fino a decode_response_body di google-apis-core. Confronta la risposta restituita in forma di array con la struttura prevista del modello generato; il lavoro è completato quando la richiesta termina senza il NoMethodError di has_key?.
