# 40134: Dequeue Instruction does not have a valid 'status\_callback\_events' parameter

Log Level: ERROR

## Description

### Possible causes

* You provided an invalid format in your "status\_callback\_events" field.

### Possible solutions

* Make certain "status\_callback\_events" contains a valid comma separated string of events to subscribe to if responding to an assignment callback
* Make certain each "DequeueStatusCallbackEvent" contains an acceptable event to subscribe to if making a `POST` /v1/Workspaces/\{WorkspaceSid}/Tasks/\{TaskSid}/Reservations/\{ReservationSid}

### Example

```bash
{
	"instruction": "dequeue",
	"to": "client:alice",
	"from": "bob",
	"post_work_activity_sid": "WA0123456789abcdef0123456789abcdef",
    "status_callback_events": "initiated,ringing,answered,completed"
}
```
