| **Common Causes**             | This error could occur when an institution does not support aggregation or some of the Open Finance products.​ ​                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               |
| **Troubleshooting Steps**     | * You can verify if the selected account type (Checking, Savings, Money Market etc.,) is supported. Prompt the end user to select a different institution or account that does support the product. * If the issue continues despite confirming that the financial institution supports the selected account type, submit a support ticket for troubleshooting. * If you consider this financial institution to be crucial for your application, email Mastercard support at [OB.Institutions@mastercard.com](mailto:OB.Institutions@mastercard.com). They can provide the status of the institution and let you know of any possibilities for future support. |
