If anyone ends up getting 400 errors form OpenAi on tool calls: https://github.com/laravel/ai/issues/313

Perhaps it'd be worth completing the messages() method in the agent in the previous video otherwise this one won't work

Something along these lines

    public function messages(): iterable
    {
        return TicketMessage::where('ticket_id', $this->ticketId)
            ->get()
            ->map(function (TicketMessage $message) {
                $role = is_null($message->user_id)
                    ? Laravel\Ai\Messages\MessageRole::Assistant
                    : Laravel\Ai\Messages\MessageRole::User;

                return new Laravel\Ai\Messages\Message($role, $message->body);
            })->toArray();
    }
