Why doesn't the Show Activity Summary generative AI action generate any output?

You can request summaries of activity records such as tasks, appointments, and interactions that are generated in real-time from Oracle's Generative AI (Gen AI) service. To generate a concise summary of recent activities, Gen AI also relies on activities having meaningful content and being correctly linked to Oracle Sales records.

You must ensure that Gen AI is fetching the required row details such as row = Object.assign({} , previous.row); from the ActivityOnCreate action chain.
