openclaw - 💡(How to fix) Fix [Feature]: Feishu channel — missing read receipts (已读回执) on DM messages [3 comments, 3 participants]

Problem

When sending DM messages to the OpenClaw Feishu bot, the "read" indicator (已读) no longer appears next to sent messages after the bot processes them. Previously this worked — the message would show "已读" once the bot had received and read it.

This makes it unclear whether the bot actually received the message or is silently ignoring it (especially relevant when the agent is stuck/processing).

Environment

• OpenClaw version: 2026.5.4
• Channel: Feishu (WebSocket mode)
• OS: Linux 6.17.0-22-generic (x64)
• Node: v22.22.2

Steps to Reproduce

1. Configure Feishu channel in WebSocket mode
2. Send a DM to the bot
3. Observe that the message never shows "已读" (read) status, even after the bot responds

Expected Behavior

Bot should mark inbound messages as read (call Feishu's read receipt API), so the sender sees the "已读" indicator — confirming the message was received and processed.

Actual Behavior

No read receipt is sent; the "已读" indicator never appears.

Notes

• The OpenClaw dist bundle includes a readReceipt module (require_read_receipt()), suggesting the mechanism exists in code
• Unlike WhatsApp (which has sendReadReceipts config), the Feishu channel config has no equivalent toggle
• Other channels (WhatsApp, BlueBubbles) explicitly support sendReadReceipts
• This may be a regression from a recent version, or the feature was never fully implemented for Feishu

Request

Please add read receipt support for the Feishu channel, similar to WhatsApp's sendReadReceipts. Either:

1. Auto-send read receipts on inbound Feishu DMs (default on)
2. Add a config option channels.feishu.sendReadReceipts: true
