Missing data in V2 REST API

Hi there!

Why does the GET https://api.revenuecat.com/v2/projects/{project_id}/products/{product_id} endpoint return the following for any subscription product until that product is purchased at least once?

{
 ...
  "subscription": {
    "duration": null,
    "grace_period_duration": null,
    "trial_duration": null
  }
 ...
}

Right after purchasing the endpoint starts to return correct data:

{
 ...
  "subscription": {
    "duration": "P1M",
    "grace_period_duration": "P3D",
    "trial_duration": "P1W"
  }
 ...
}

Is V2 REST API production ready?
