| **Error Message**             | Error while processing payment routing.                                                                                                                                                                                                                                                                                                                                                       |
| **Common Causes**             | This can occur if there are errors or invalid information in the payment information you include in your request.                                                                                                                                                                                                                                                                             |
| **Troubleshooting Steps**     | * Double-check the information included in your request, such as `customerId`, `accountId`, and `settlementAmount` or `settleByDate`. Any errors in this information can cause this issue. * Review and resend the request. * If the issue persists, submit a [support ticket](https://developer.mastercard.com/open-finance-us/documentation/support/index.md#create-a-support-case-in-scm). |
