Error preventing the return of a Query Response

When a Data Source system encounters an error that prevents it from responding to a Query message with a Query Response, it SHALL respond by returning a Error message containing an OperationOutcome resource that describes the nature of the failure.

The OperationOutcome:

• SHALL contain a definition of severity in the OperationOutcome.issue.severity field.
• SHALL contain a definition of the type of error in the OperationOutcome.issue.code element.
• SHOULD provide additional diagnostic details of the error in OperationOutcome.diagnostics property
• SHOULD contain details of the error in the OperationOutcome.issue.details.coding.display field.
• SHOULD contain an OperationOutcome.issue.details.coding.code value.
