The failure occurs when Cielo returns null values for the 3DS2 authentication parameters, causing the authorization to be rejected. The issue affects debit transactions in general, regardless of card brand or issuing bank.\n\n## Simulation\n\nUnable to reproduce. The failure occurs randomly — some debit transactions complete successfully while others fail under identical conditions.\n\n## Workaround\n\nNot available."}
