This is how I present the free time slots to VAPI Are you presenting them like this?

{
  "2024-09-25": [
    {
      "start": "09:00",
      "end": "09:30"
    },
    {
      "start": "10:00",
      "end": "10:30"
    }
  ],
  "2024-09-26": [
    {
      "start": "11:00",
      "end": "11:30"
    },
    {
      "start": "13:00",
      "end": "13:30"
    }
  ]
}
