I get following error on finishing my passkey created on my android app with android 14:

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "publicKeyAlgorithm" (class com.yubico.webauthn.data.AuthenticatorAttestationResponse), not marked as ignorable (3 known properties: "transports", "clientDataJSON", "attestationObject"])

The generated publicCredential looks like this:

{
	"rawId": "2nTIub3-qA3CCizxdL2DlA",
	"authenticatorAttachment": "platform",
	"type": "public-key",
	"id": "2nTIub3-qA3CCizxdL2DlA",
	"response": {
		"clientDataJSON": "eyJ0eXBlIjoid2ViYXV0aG4uY3JlYXRlIiwiY2hhbGxlbmdlIjoiUDZCQkxiOHR2Q1A0N3dsb0JKdVl5cXR2bnkzbWk1QmRuR2FmXzBBZkcwbyIsIm9yaWdpbiI6ImFuZHJvaWQ6YXBrLWtleS1oYXNoOjB1YWV0UDVsQ3VkY3MwMmxaWDJadVgzS3VRSVY0TnFiamJaNnROd3E3UmciLCJhbmRyb2lkUGFja2FnZU5hbWUiOiJtZS5pbnN0YWhlbHAubGVnYWN5In0",

	},
	"clientExtensionResults": {

}

It looks that the request should be allowed per spec: https://w3c.github.io/webauthn/#authenticatorattestationresponse

Is this a bug?
