For example, our parser may trigger an exception and cancel the transaction.\n\n\n##\n\n## Simulation\n\n\nTo simulate this issue, we used our legacy MercadoPagoV1 connector to place an order and passed user phone data with less than three digits.\n\n\n##\n\n## Workaround\n\n\nUnfortunately, there is no workaround at this time. To avoid this issue, we recommend ensuring that all user data is properly validated before being sent to the gateway."}
