Message Duplication When Sending Multiple Attachments via Chatwoot + Evolution API v2.3.0 #1681
Description
Welcome!
- Yes, I have searched for similar issues on GitHub and found none.
What did you do?
When sending a message through Chatwoot integrated with the Evolution API (WhatsApp), containing text and multiple attachments (e.g., images, PDFs) in a single payload, the text is repeated for each file—resulting in duplicate messages on WhatsApp.
Steps to Reproduce:
Use Evolution API v2.3.0 integrated with Chatwoot.
Send a message with text and two or more attachments in a single payload.
Observe that the recipient receives the text multiple times, each accompanied by a different attachment.
What did you expect?
The text should be sent only once, followed by multiple attachments without repetition.
What did you observe instead of what you expected?
The text is repeated for each attachment, causing redundant messages.

Additional Notes
Possible Root Cause:
This issue appears to be related to how the API iterates over each attachment and reuses the same text block without checking if it's already been sent. A similar issue was reported in previous versions.

Suggested Fix:
Group attachments under a single message context.
Flag the text to be sent only once per batch.
