Apple /v1/attestationData endpoint returning 400 request with valid receipt base64 data

Hello,

I am sending valid base64 receipt data to Apple on the https://data-development.appattest.apple.com/v1/attestationData endpoint and am getting 400 bad request. I have a valid JWT that I currently use successfully for other DeviceCheck endpoints such as persistent bits.

Any help debugging would be useful. Thanks

Figured this out, I was using the wrong entitlements
