App attest api returns "DCErrorInvalidKey 3" invalidKey error in iOS 17 beta

Hi, App Attestation API "attest key" returns "DCErrorInvalidKey 3" in iOS 17 beta with these parameters keyId: "IAeivHRAmm8gDFuNfRbRGAt4n7AuJ1msWEgdMUGHEV8=" and challenge: "9132b01acd5d416369382950be1f421e"

tried on device model: XSMax.

Note: I tried same challenge on another phone and it works fine.

Hi, did you happen to figure out anything here @Israa? I am facing the same problem for iOS beta. On trying to attest a newly generated key it's giving back an invalidKey for iOS 17 betas.

App Attestation always return same error on iPhone 8 with iOS 16.7.2, we did restart iPhone, reinstall app and it is still the same. We have customers who are also affected.
