## 🔍 Troubleshooting

### AppWrite-Specific Issues

### AppWrite-Specific Issues

#### CORS (Cross-Origin Resource Sharing) Problems
**Symptom**: "Access to fetch at 'https://appwrite.webklar.com/v1/account/sessions/email' from origin 'https://www.amazon.de' has been blocked by CORS policy"

**Root Cause**: Your AppWrite server is configured to only allow `https://localhost` but the extension runs on Amazon domains (amazon.de, amazon.com, etc.).

**Automatic Solution**: The extension automatically detects CORS errors and falls back to localStorage:
1. Extension attempts AppWrite operation
2. CORS error is detected by ErrorHandler
3. Extension automatically switches to localStorage fallback mode
4. All data is saved locally and queued for later synchronization
5. User sees notification: "Cloud-Service nicht verfügbar. Daten werden lokal gespeichert."

**Manual Solutions**:
1. **Fix AppWrite CORS Settings** (Recommended):
   - Go to your AppWrite console
   - Navigate to "Settings" → "Platforms" 
   - Add a new "Web Platform"
   - Set hostname to `*.amazon.*` (wildcard for all Amazon domains)
   - Or add specific domains: `amazon.de`, `amazon.com`, `amazon.co.uk`, etc.

2. **Use AppWrite Cloud** (Alternative):
   - Migrate to AppWrite Cloud (cloud.appwrite.io)
   - AppWrite Cloud has better CORS configuration options
   - Follow the same setup process with your new endpoint

3. **Local AppWrite Instance** (Development):
   - Run AppWrite locally with Docker
   - Configure CORS to allow all origins during development
   - Use `http://localhost/v1` as endpoint

**Debug Commands**:
```javascript
// Check if CORS fallback is active
window.errorHandler.isUsingLocalStorageFallback();

// Check AppWrite status
window.errorHandler.getAppWriteStatus();

// Test CORS fallback manually
window.amazonExtEventBus.emit('appwrite:test-cors');
```

#### Collection Permissions Issues
**Symptom**: "401 Unauthorized - The current user is not authorized to perform the requested action"

**Root Cause**: Your AppWrite collections have incorrect permissions. Users cannot read/write their own data.

**Solution**: Fix collection permissions in AppWrite console:

1. **Go to AppWrite Console** → Databases → `amazon-extension-db`
2. **For each collection**, click on it and go to "Settings" tab
3. **Set these exact permissions**:
   - **Create**: `users` (any authenticated user can create)
   - **Read**: `user:$userId` (users can only read their own documents)
   - **Update**: `user:$userId` (users can only update their own documents)
   - **Delete**: `user:$userId` (users can only delete their own documents)

4. **Apply to all 5 collections**:
   - `amazon-ext-enhanced-items`
   - `amazon-ext-saved-products`
   - `amazon_ext_blacklist`
   - `amazon-ext-enhanced-settings`
   - `amazon-ext-migration-status`

**Alternative Quick Fix**: Set all permissions to `users` temporarily for testing, then restrict to `user:$userId` for production.

**Debug Commands**:
```javascript
// Check current user authentication
window.authService.getCurrentUser();

// Test collection access
window.appWriteManager.listDocuments('amazon-ext-enhanced-items');
```

#### Collection Schema Issues
**Symptom**: "Invalid query: Attribute not found in schema: userId"

**Root Cause**: Your AppWrite collections are missing the required `userId` attribute that the extension needs for user data isolation.

**🔧 AUTOMATED REPAIR SOLUTION** (Recommended):
1. **Open Repair Tool**: Navigate to `test-appwrite-repair-tool.html` in your browser
2. **Configure Connection**: Enter your AppWrite endpoint, project ID, API key, and database ID
3. **Run Analysis**: Click "Nur Analyse" to safely check all collections
4. **Review Results**: Check which collections need the userId attribute
5. **Execute Repair**: Click "Reparatur starten" to automatically fix all issues
6. **Verify Success**: The tool will validate all repairs and provide a comprehensive report

**📖 Detailed Repair Guide**: See `APPWRITE_REPAIR_TOOL_GUIDE_DE.md` for complete instructions

**Manual Solution** (if automated repair fails):
1. **Go to AppWrite Console** → Databases → `amazon-extension-db`
2. **For each collection**, click on it and go to "Attributes" tab
3. **Add `userId` attribute**:
   - Type: String
   - Key: `userId`
   - Size: 255
   - Required: Yes
   - Array: No
4. **Repeat for all 5 collections**:
   - `amazon-ext-enhanced-items`
   - `amazon-ext-saved-products`
   - `amazon_ext_blacklist`
   - `amazon-ext-enhanced-settings`
   - `amazon-ext-migration-status`

**Quick Fix**: See `APPWRITE_COLLECTION_SETUP.md` for detailed manual setup instructions.

**Debug Commands**:
```javascript
// Check if collections are accessible
window.appWriteManager.healthCheck();

// Test collection access
window.appWriteManager.listDocuments('amazon-ext-enhanced-items');
```

#### Connection Problems
**Symptom**: "AppWrite connection failed" error
**Solutions**:
1. Verify AppWrite endpoint URL in `src/AppWriteConfig.js`
