API Missing athlete's training plan

Actual Behavior:
I’m encountering an issue when querying the following endpoint:
GET /api/v1/athlete/{id}/training-plan.

Despite using a valid athleteId (confirmed to work with other endpoints such as wellness and activities), the response consistently returns null values:

{
  "athlete_id": null,
  "training_plan_id": null,
  "training_plan_start_date": null,
  "timezone": null,
  "training_plan_last_applied": null,
  "training_plan": null,
  "training_plan_alias": null
}

Expected Behavior:
I expect the endpoint to return the associated training plan data for the specified athlete, assuming a training plan has been created properly:

Doesn’t work for me either. Could you look at that @david
