50504: Programmable Chat: Message body parameter is too long

This error occurs when you create or update a Programmable Chat message with a Body that exceeds the allowed message size. Programmable Chat limits Message Body to 32 KiB.

• The Body value in your message request is larger than the 32 KiB limit for a Chat message body.
• Your application serializes structured data into Body, which makes the message content too large. Twilio allows structured data in Body when you serialize it as a string, so oversized serialized payloads can trigger this error.
• A pre-event webhook for onMessageSend or onMessageUpdate modifies body before the message is published and pushes it past the allowed limit.

• Reduce the Body value so it stays within the 32 KiB message body limit.
• Validate message length in your application before you create or update a message.
• If you use pre-event webhooks, review your onMessageSend and onMessageUpdate logic and make sure the returned body does not exceed the message size limit.
• Keep Body focused on message text. If you send structured data in Body, reduce the serialized payload so it fits within the limit.
