API-specific error codes

Error Code	Description	Reason / When It Occurs
748	No metadata update requested.	The request did not include any updatable fields (e.g., no new bill number, bill ID, or purpose provided).
749	Exactly one redemption identifier needed to identify redemption.	You must pass only one valid identifier (`redemptionId`, `billNumber`, or another allowed ID). Passing none or multiple identifiers triggers this error.
750	Redemption update failed: 0.	The update action failed internally, possibly due to invalid status transitions or data integrity issues. `{0}` provides specific details.
1219	Entity details not set/invalid.	The `entity` object is missing or its fields (`type`, `identifierType`, `identifierValue`) are incomplete or invalid.
1212	Entity type passed is not valid.	The `entity.type` value (e.g., `CUSTOMER`, `groupUser`) is incorrect or not supported for your configuration.
8015	Invalid or malformed identifier provided in request body.	The `identifierValue` or `redemptionId` is missing, incorrectly formatted, or does not exist in the system.
