Handle Missing BPN Names in IRS Job Response

[ds-mwesener]

As a system integrator, I want to ensure that the attributes sentToName and createdByName are populated correctly, so that our notification system functions as intended even when the IRS does not deliver BPN names within their jobResponse.

Hints / Details

• The IRS no longer delivers BPN names within their jobResponse, which results in sentToName and createdByName attributes being null.
• We need to either ensure that the bpdmClient works correctly to retrieve the BPN names, or manage the BPN names ourselves.
• Investigate and decide the best approach: fixing the bpdmClient or implementing an alternative method to handle BPN names.
• Ensure backward compatibility with the current system.

Acceptance Criteria

• The sentToName and createdByName attributes are correctly populated for notifications.
• If the bpdmClient is used, it retrieves and integrates BPN names accurately.
• If an alternative method is implemented, it effectively manages and integrates BPN names.
• Proper error handling and logging are in place for scenarios where BPN names cannot be retrieved.
• Comprehensive unit and integration tests are created to validate the solution.

Out of Scope

• Changes to the IRS jobResponse structure.
• Modifications to other unrelated components of the notification system.
