21619: A Message Body, Media URL or Content SID is required

This error occurs when you create a Message with a Messaging Service and do not provide any message content. Include content in Body, MediaUrl, or ContentSid.

• Your request includes MessagingServiceSid but omits Body, MediaUrl, and ContentSid.
• Your application sends an empty or undefined Body and does not provide MediaUrl or ContentSid.
• You are trying to send a content template without including ContentSid.

• Include at least one content parameter in your request: Body, MediaUrl, or ContentSid.
• If you are sending plain text, pass the text in Body.
• If you are sending media, include one or more MediaUrl values.
• If you are sending a template created with the Content Template Builder, include ContentSid. Include ContentVariables when your template contains placeholders.
• Review your request builder or helper library code to make sure it is not stripping all content fields before the API request is sent.
