54251: Invalid Message Stream Message data

This error occurs when you create a Sync Stream Message without the required Data value. A Stream Message body must contain an arbitrary JSON object. If you call the REST API directly, send Data as a JSON string in an application/x-www-form-urlencoded request.

• The request to create the Stream Message did not include the required Data parameter.
• The Data parameter was sent with a null value.
• The request body did not provide the message payload in a valid JSON format for the API request you used.

• Add the Data parameter to the request body when you publish the Stream Message.
• Send a non-null JSON payload for the message body.
• If you call the REST API directly, serialize the message body as a JSON string before sending the request.
• If you use a Twilio helper library, pass a non-null object to data when you create the Stream Message.
• Make sure the serialized message body does not exceed the 4 KiB limit.
