+# Fix NextAuth CLIENT_FETCH_ERROR on Vercel
+
+## Problem
+```
+[next-auth][error][CLIENT_FETCH_ERROR]
+https://next-auth.js.org/errors#client_fetch_error undefined
+```
+
+This error occurs when NextAuth environment variables are missing or incorrectly configured on Vercel.
+
+## Solution: Set Environment Variables on Vercel
+
+### 1. Generate NEXTAUTH_SECRET
+
+Run this command to generate a secure secret:
+
+```bash
+openssl rand -base64 32
+```
+
+Copy the output (something like: `jK8mN2pQ5rS7tU9vW0xY1zA3bC4dE5fF6gH7iJ8kL9mN0oP1qR2sT3u=`)
+
+### 2. Add Environment Variables to Vercel
+
+Go to your Vercel project settings:
+
+**Vercel Dashboard → Your Project → Settings → Environment Variables**
+
+Add these variables:
+
+#### Required Variables
+
+| Variable | Value | Notes |
+|----------|-------|-------|
+| `NEXTAUTH_URL` | `https://miku-two.vercel.app` | Your full Vercel deployment URL |
+| `NEXTAUTH_SECRET` | `<generated_secret>` | The secret from step 1 |
+| `DISCORD_CLIENT_ID` | `<your_discord_app_client_id>` | From Discord Developer Portal |
+| `DISCORD_CLIENT_SECRET` | `<your_discord_app_client_secret>` | From Discord Developer Portal |
+| `BOT_API_URL` | `https://miku-fjwa.onrender.com` | Your Render backend URL |
+
+#### Important Settings
+
+For each environment variable:
+- ✅ Check **Production**
+- ✅ Check **Preview**
+- ✅ Check **Development** (optional)
+
+### 3. Update Discord OAuth2 Redirect URL
+
+Go to **Discord Developer Portal → Your App → OAuth2 → Redirects**
+
+Add/Update redirect URL:
+```
+https://miku-two.vercel.app/api/auth/callback/discord
+```
+
+### 4. Redeploy
+
+After adding environment variables, trigger a new deployment:
+
+**Option A - Via Vercel Dashboard:**
+- Go to **Deployments** tab
+- Click **⋯** on the latest deployment
+- Click **Redeploy**
+
+**Option B - Via Git Push:**
+```bash
+git commit --allow-empty -m "Trigger redeploy"
+git push
+```
+
+### 5. Verify
+
+After deployment completes:
+
+1. Visit `https://miku-two.vercel.app`
+2. Click "Sign in with Discord"
+3. You should be redirected to Discord OAuth
+4. After authorization, you should be redirected back and signed in
+
+Check Vercel logs for any remaining errors:
+- Go to **Deployments** → Click latest deployment → **Runtime Logs**
+
+## Common Issues
+
+### Issue: Still getting CLIENT_FETCH_ERROR
+
+**Solution:** Clear browser cookies and try again:
+```
+1. Open browser DevTools (F12)
+2. Application/Storage tab
+3. Clear cookies for miku-two.vercel.app
+4. Refresh and try signing in again
+```
+
+### Issue: OAuth redirect mismatch
+
+**Solution:** Ensure Discord redirect URL EXACTLY matches:
+```
+https://miku-two.vercel.app/api/auth/callback/discord
+```
+- No trailing slash
+- Must use https
+- Must match your NEXTAUTH_URL
+
+### Issue: Session not persisting
+
+**Solution:** Ensure cookies are not blocked:
+- Check browser privacy settings
+- Try in incognito/private mode
+- Check browser console for cookie warnings
+
+## Environment Variable Checklist
+
+Copy this checklist and verify each variable:
+
+```
+Vercel Environment Variables (https://vercel.com/your-account/miku-two/settings/environment-variables):
+
+[ ] NEXTAUTH_URL = https://miku-two.vercel.app
+[ ] NEXTAUTH_SECRET = <32+ character random string>
+[ ] DISCORD_CLIENT_ID = <from Discord Developer Portal>
+[ ] DISCORD_CLIENT_SECRET = <from Discord Developer Portal>
+[ ] BOT_API_URL = https://miku-fjwa.onrender.com
+
+Discord OAuth2 Redirects (https://discord.com/developers/applications):
+
+[ ] https://miku-two.vercel.app/api/auth/callback/discord
+
+Deployment:
+
+[ ] Redeployed after adding environment variables
+[ ] No errors in Vercel Runtime Logs
+[ ] Successfully signed in with Discord
+```
+
+## Technical Details
+
+### What Changed
+
+Added explicit NextAuth configuration in `[...nextauth].ts`:
+
+```typescript
+export const authOptions: NextAuthOptions = {
+  secret: process.env.NEXTAUTH_SECRET,  // Now explicitly required
+  session: {
+    strategy: 'jwt',
+    maxAge: 30 * 24 * 60 * 60,  // 30 days
+  },
+  cookies: {
+    sessionToken: {
+      name: `${process.env.NODE_ENV === 'production' ? '__Secure-' : ''}next-auth.session-token`,
+      options: {
+        httpOnly: true,
+        sameSite: 'lax',
+        path: '/',
+        secure: process.env.NODE_ENV === 'production',
+      },
+    },
+  },
+  // ... rest of config
+}
+```
+
+### Why This Fixes It
+
+1. **Explicit secret**: NextAuth now explicitly uses `NEXTAUTH_SECRET` environment variable
+2. **Production cookies**: Uses secure cookies in production (`__Secure-` prefix, `secure: true`)
+3. **Session strategy**: Explicitly sets JWT strategy with 30-day expiration
+4. **Cookie settings**: Properly configured for Vercel's serverless environment
+
+## Support
+
+If you continue to have issues after following this guide:
+
+1. Check Vercel Runtime Logs for specific errors
+2. Check browser console (F12) for client-side errors
+3. Verify all environment variables are set correctly
+4. Try clearing all cookies and cache
+5. Test in incognito/private browsing mode
