Hi,

I'm decoding an attestationObject created with ASAuthorizationPlatformPublicKeyCredentialRegistration, but the results have no statement:

{'fmt': 'none', 'attStmt': {}, 'authData': '.....data here.......'}

The whole credentialRegistration.rawAttestationObject is 182 bytes

I'm expecting to see keys like: sig, x5c, alg, certInfo, pubArea etc, but the dictionary is empty, any ideas why it would be empty?
