2.  Select **New**.

3.  From **Flow/SubFlow/Action**, select Flow.

4.  From **Document**, select the flow that you want to publish a system event for when it enters an unexpected state.

    |Published presumed interrupted events|Publish a system event when a flow enters the Presumed Interrupted state.|

7.  In **Event name**, enter a custom event name.

    These are the default system event names.

    -   **flow.state.error**
    -   **flow.state.cancelled**
    -   **flow.state.interrupted**
8.  Select **Submit**.


## Result

Workflow Studio publishes the appropriate system event when the flow enters the specified unexpected state of error, cancelled, or presumed interrupted. You can review the **Parm2** field of the system event to see a JSON payload describing the flow context.

```json
{
  "contextId": "abc123...",
  "flowId": "def456...",
  "flowName": "My Automated Flow",
  "previousState": "IN_PROGRESS",
  "currentState": "ERROR",
  "errorMessage": "Connection timeout",
  "cancellationReason": "",
  "runTimeMs": 1542,
  "engineMajorVersion": 2,
  "domainId": "global",
  "createdBy": "admin",
  "callingSource": "flow_trigger"
}
```

## What to do next

Register the system event. For more information about registering a system event, see [Register an event](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/system-events/t_RegisterAnEvent.md). After the system event is registered, you can create a script action or a notification to automate the response to the event. For more information about script actions, see [Script actions](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/build-workflows/system-events/r_ScriptActions.md).
