Device Check API returns 500

Hi everyone,

Currently, our team is trying to implement Device Check API. We have an issue, when we perform a POST request to Device Check API we always get 500 without error message from Apple server.

Device token and JWT token looks fine, we don't get 400 or 401 status codes, it always 500. In which context 500 errors can occur every time?

Thanks in advance,

Arseniy
