RestAPI in sandbox always return null to subscriber node

Hi,

We’ve been sending requests to the following endpoint: https://api.revenuecat.com/v1/subscribers/{{id}}.

curl --request GET \
    --url 'https://api.revenuecat.com/v1/subscribers/<app_user_id>' \
    --header 'accept: application/json' \
    --header 'authorization: Bearer <my_v1_token>'

In the request we DON’T send the optional parameter: “X-Is-Sandbox”: https://www.revenuecat.com/docs/api-v1#tag/customers/operation/subscribers

On the production environment, we have the following json response.

{
  ...
  "subscriber": {
        "entitlements": {
            "entitlement_identify": {
                "expires_date": "YYYY-MM-ddTHH:mm:ssZ",
                "grace_period_expires_date": null,
                "product_identifier": "product_identifier",
                "purchase_date": "YYYY-MM-ddTHH:mm:ssZ",
            }
        },
   }
   ...
}

We look for the subscriber node to make user’s subscription validation.
 

But in the last 3 days we’ve been experiencing trouble in the sandbox environment.

The current json response is:

{
  ...
  "subscriber": {
        "entitlements": {},
   }
   ...
}

And this occur in many applications that we have.

Is it possible that there something isn’t working in sandbox environment?

Or maybe the endpoints has being changed?

Could you help us?

Thanks in advance,

Regards.
