AppAccountToken is missing

Hello I've problem with transaction payload. If I receive POST App Store notification v2 to my server. In the decoded transaction body is missing appAccountToken field. In the iOS app I've just set token like this:

        
        let result = try await product.purchase(options: [
            .appAccountToken(UUID.encodeIntAsUUID(Auth.shared.user.idUser)),
            .simulatesAskToBuyInSandbox(true)
        ])

Where is the problem?
