Button messages (sendButtons) return 201 but are never delivered to WhatsApp

Welcome!

• Yes, I have searched for similar issues on GitHub and found none.

What did you do?

Environment
• Evolution API version: 2.3.*
• Deployment: Self-hosted (Docker)
• WhatsApp library: Baileys (via Evolution)
• Client: Postman / cURL
• Instance type: WhatsApp Web
• Number: Regular WhatsApp number (not Business API)

Sending text messages using sendText works correctly and messages are delivered.

However, when sending button messages using sendButtons, the API returns HTTP 201 (Created) and a valid response payload, but the message is never delivered to the recipient’s WhatsApp client (mobile or web).

There are no errors returned by the API, and the message status remains PENDING.

Thanks for the help :)
