Installation Errors

Error 1: Node.js Version Mismatch

Error message:

OpenClaw requires Node.js 22 or higher. Current: 18.x.x

Cause: OpenClaw uses APIs only available in Node 22+. Node 18 and 20 LTS are not supported.

Fix:

# Install and use Node 22 via nvm
nvm install 22
nvm use 22
node --version  # Must show v22.x.x

---

Error 2: Command Not Found

Error message:

Fix:

# Recommended: use nvm (avoids permission issues entirely)

sudo chown -R $USER $(npm config get prefix)

Cause: API key is missing, expired, or has extra whitespace.

Discord Errors

Bot Shows as Offline

Checklist:

1. Run openclaw status — ensure service is running
2. Verify bot token in .env is correct
3. Run openclaw logs and look for connection errors

---

Bot is Online but Doesn't Respond

Critical fix — this is the #1 Discord issue in 2026:

1. Open Discord Developer Portal
2. Select your application → Bot → Privileged Gateway Intents
3. Enable "Message Content Intent" — without this, the bot can't read messages
4. Save, then restart OpenClaw

---

Slash Commands Not Appearing

Fix:

1. Wait 1–5 minutes after registering commands (Discord propagation delay)
2. Ensure applications.commands scope was selected when inviting the bot
3. Fully quit and reopen Discord

---

Error Prevention Checklist

Follow these practices to avoid errors before they happen:

Practice	Why It Helps
Use Node.js 22+ (not 18/20)	OpenClaw's hard requirement
Keep OpenClaw updated	Bug fixes ship in updates
Validate JSON before saving	Syntax errors are hard to spot
Check openclaw logs first	Most issues are logged clearly
Back up config before changes	Easy rollback if something breaks
Never commit .env to git	Prevents API key exposure

---
