SyncError Event

Event-name: SyncError

Workflow

A synchronization error has been detected and this is indicated to Subscribers.

Unlike most of FHIRcast events, SyncError is an infrastructural event and does not follow the FHIR-resource-[open|close] syntax and is directly referenced in the underlying specification.

A SyncError is sent by a Subscriber when:

1. It responds to a context change event with a 202 indicating the context change is accepted but has not yet occurred, and later the Subscriber decides to refuse the context (see: Event Notification Response).

In these events the field issue.severity is SHALL be set to warning as is specified in Operation outcome for Subscriber generated sync-errors.

A SyncError is broadcast by the Hub when one of the following conditions occur:

1. A Subscriber encounters an error when following a context, returning a server error (50X) to the Hub (see: Event Notification Response).
2. A Subscriber decides not to follow a context, returning a server conflict (409) to the Hub (see: Event Notification Response).
3. The Hub detects a connection issue with a Subscriber (see: Hub Generated SyncError Events).

In these events the field issue.severity SHALL beset to warning as is specified in Operation outcome for Hub generated sync-errors.

Context

The context array SHALL contain a single FHIR OperationOutcome based on the profile Operation outcome for sync-errors.
