+# C3 Troubleshooting
+
+## Deployment Issues
+
+### Placeholder IDs
+
+**Error:** "Invalid namespace ID"  
+**Fix:** Replace placeholders in wrangler.jsonc with real IDs:
+```bash
+npx wrangler kv namespace create MY_KV  # Get real ID
+```
+
+### Authentication
+
+**Error:** "Not authenticated"  
+**Fix:** `npx wrangler login` or set `CLOUDFLARE_API_TOKEN`
+
+### Name Conflict
+
+**Error:** "Worker already exists"  
+**Fix:** Change `name` in wrangler.jsonc
+
+## Platform Selection
+
+| Need | Platform |
+|------|----------|
+| Git integration, branch previews | `--platform=pages` |
+| Durable Objects, D1, Queues | Workers (default) |
+
+Wrong platform? Recreate with correct `--platform` flag.
+
+## TypeScript Issues
+
+**"Cannot find name 'KVNamespace'"**
+```bash
+npm run cf-typegen  # Regenerate types
+# Restart TS server in editor
+```
+
+**Missing types after config change:** Re-run `npm run cf-typegen`
+
+## Package Manager
+
+**Multiple lockfiles causing issues:**
+```bash
+rm pnpm-lock.yaml  # If using npm
+rm package-lock.json  # If using pnpm
+```
+
+## CI/CD
+
+**CI hangs on prompts:**
+```bash
+npm create cloudflare@latest my-app -- \
+  --type=hello-world --lang=ts --no-git --no-deploy
+```
+
+**Auth in CI:**
+```yaml
+env:
+  CLOUDFLARE_API_TOKEN: ${{ secrets.CLOUDFLARE_API_TOKEN }}
+  CLOUDFLARE_ACCOUNT_ID: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
+```
+
+## Framework-Specific
+
+| Framework | Issue | Fix |
+|-----------|-------|-----|
+| Next.js | create-next-app failed | `npm cache clean --force`, retry |
+| Astro | Adapter missing | Install `@astrojs/cloudflare` |
+| Remix | Module errors | Update `@remix-run/cloudflare*` |
+
+## Compatibility Date
+
+**"Feature X requires compatibility_date >= ..."**  
+**Fix:** Update `compatibility_date` in wrangler.jsonc to today's date
+
+## Node.js Version
+
+**"Node.js version not supported"**  
+**Fix:** Install Node.js 18+ (`nvm install 20`)
+
+## Quick Reference
+
+| Error | Cause | Fix |
+|-------|-------|-----|
+| Invalid namespace ID | Placeholder binding | Create resource, update config |
+| Not authenticated | No login | `npx wrangler login` |
+| Cannot find KVNamespace | Missing types | `npm run cf-typegen` |
+| Worker already exists | Name conflict | Change `name` |
+| CI hangs | Missing flags | Add --type, --lang, --no-deploy |
