Code 400. Google service account key is not set in Adapty dashboard

Hey guys, we're trying to implement Adapty Android SDK and facing the following error:
E/Adapty_v1.4.0: Request is unsuccessful. https://api.adapty.io/api/v1/sdk/in-apps/google/token/restore/ Code: 400, Response: {"errors":[{"detail":"Google service account key is not set in Adapty dashboard.","status":"400","source":{"pointer":"/data"},"code":"GOOGLE_SERVICE_ACCOUNT_KEY_IS_NOT_SET_ERROR"}]}

I am not really sure what might be causing this. Can you look into this?
