Replay Guard Blocks Duplicate Messages | Generated by AI

Home 2026.04

I found the issue. Here’s what’s happening:

Problem Analysis:

  1. Your requireMention: false config IS correct — it’s at rooms.eu42ecdy.requireMention, which is the right place.

  2. The real issue: Replay Guard deduplication
    • The dedupe file shows: {"eu42ecdy:1": 1775323541972}
    • This means messages with messageId=1 from room eu42ecdy are being blocked as duplicates for 24 hours (TTL = 86400000ms)
    • Every message with messageId=1 after the first is rejected BEFORE the mention check even runs
  3. Flow: shouldProcessMessage (replay check) → if passed → handleNextcloudTalkInbound → mention gate check

The replay guard runs FIRST, so even with requireMention: false correctly set, duplicate message IDs get blocked before reaching the mention logic.

Likely cause: Nextcloud Talk is sending the same messageId for all messages (or you’re resending the same test webhook).

Fix options:

  1. Quick fix — clear the replay dedupe file: 
    rm /home/lzw/.openclaw/nextcloud-talk/replay-dedupe/*.json
echo '{}' > /home/lzw/.openclaw/nextcloud-talk/replay-dedupe/*.json

    Then send a new message with a unique ID.

  2. Or restart the gateway to pick up the config fresh.

  3. Check Nextcloud Talk — ensure it’s generating unique message IDs for each message, not reusing 1.

Want me to clear the dedupe file and verify the config?
