Summary

After upgrading OpenClaw to 2026.4.27 (cbc2ba0), Discord channel/group-chat runs were completing internally, but no final assistant response was visibly posted back to Discord.

The working fix was to set:

{
  "messages": {
    "groupChat": {
      "visibleReplies": "automatic"
    }
  }
}

and then restart the gateway.

Symptom

• Discord channel message triggers OpenClaw normally.
• The agent run completes successfully.
• Tool calls / internal processing work.
• The final response is not visible in the Discord channel.
• No obvious runtime failure is shown from the user side.

Expected behavior

After an upgrade, existing Discord channel/group-chat reply behavior should either:

1. continue working with visible final replies, or
2. be migrated/warned clearly if a config value now suppresses visible replies.

Actual behavior

Replies completed internally but Discord stayed silent until messages.groupChat.visibleReplies was set to automatic.

Suggested fix

One of these would help prevent upgrade confusion:

• add/verify a config migration that preserves visible Discord channel replies,
• make automatic the safe default where appropriate, or
• have openclaw doctor warn when Discord is configured and messages.groupChat.visibleReplies is likely to suppress visible channel replies.

Environment

• OpenClaw: 2026.4.27 (cbc2ba0)
• Channel: Discord channel/group chat
• Confirmed workaround: set messages.groupChat.visibleReplies = "automatic" and restart gateway
