# 90029: Broadcast 'CorrelationId' is empty

Log Type: APPLICATION

Log Level: ERROR

## Description

You sent a broadcast request with an empty `CorrelationId` value. Provide a non-empty `CorrelationId` so Twilio can associate the broadcast request with your application context.

### Possible causes

* The `CorrelationId` field was included in the request, but its value was an empty string
* Your application trimmed or cleared the `CorrelationId` value before sending the request
* A variable used to populate `CorrelationId` was unset, null, or resolved to an empty value in your request-building logic

### Possible solutions

* Set `CorrelationId` to a non-empty string before you send the broadcast request
* Validate request payloads in your application so empty string values are rejected before submission
* Review any templating, serialization, or variable-mapping logic that populates `CorrelationId`
* If you do not need application correlation for this request, remove the field only if the API operation allows it. Otherwise, send a valid non-empty value
