apimatic\jsonmapper\JsonMapperException Could not find required constructor arguments for PaypalServerSdkLib\Models\NetworkTransactionReference: id
Paypal API does not send id for co-branding cards pay in order.payments.captures[0].network_transaction_reference.network = "PULSE"
It's reproduced when order.payment_source.available_networks = ["VISA", "PULSE"]
I guess paypal chooses more cheap channel for transaction in production, therefore it's not reproduced in sandbox.
