ios – How to validate from the backend that the user is on free trial period?

I have enabled introductory offer for 3 days in my app store connect subscription.

But when i am validating the receipt data through backend everytime I am getting [is_trial_period] => false
[is_in_intro_offer_period] => false

Why so?

enter image description here

I have created 3 day trial period with no end date.

but always getting response
