A collection of error, warning or information messages that result from a system action.

Can result from the failure of a REST call or be part of the response message returned from a request message. If sent with extensions overriding particular issues, might even appear as part of a request message.

An error, warning or information message that results from a system action.

Indicates whether the issue indicates a variation from successful processing.

Indicates how relevant the issue is to the overall success of the action.

This is labeled as "Is Modifier" because applications should not confuse hints and warnings with errors.

Describes the type of the issue. The system that creates an OperationOutcome SHALL choose the most applicable code from the IssueType value set, and may additional provide its own code for the error in the details element.

Expresses the issue in a human and computer-friendly way, allowing the requesting system to behave differently based on the type of issue.

Additional details about the error. This may be a text description of the error, or a system code that identifies the error.

A human readable description of the error issue SHOULD be placed in details.text.

Additional diagnostic information about the issue. Typically, this may be a description of how a value is erroneous, or a stack dump to help trace the issue.

Typically this field is used to provide troubleshooting information about the error.

For resource issues, this will be a simple XPath limited to element names, repetition indicators and the default child access that identifies one of the elements in the resource that caused this issue to be raised. For HTTP errors, will be "http." + the parameter name.

Allows systems to highlight or otherwise guide users to elements implicated in issues to allow them to be fixed more easily.

The root of the XPath is the resource or bundle that generated OperationOutcome. Each XPath SHALL resolve to a single node. The XPath syntax is used whether the referenced instance is expressed in XML or JSON. Note that expression is being trialed as an alternative to XPath.

A simple FHIRPath limited to element names, repetition indicators and the default child access that identifies one of the elements in the resource that caused this issue to be raised.

Allows systems to highlight or otherwise guide users to elements implicated in issues to allow them to be fixed more easily.

The root of the FHIRPath is the resource or bundle that generated OperationOutcome. Each FHIRPath SHALL resolve to a single node.
