## ✅ Fixed Bugs

### 1. **Console.error Statements in Production Code**
**Severity:** Medium
**Location:** Frontend
**Files Affected:**
- `frontend/src/App.tsx`
- `frontend/src/lib/api.ts`
- `frontend/src/components/integration/BotIntegration.tsx`

**Issue:**
Console.error statements were left in production code, which can expose sensitive error information in browser console and impact performance.

**Fix Applied:**
- Removed console.error from session check in App.tsx
- Removed console.error from logout handler in App.tsx
- Removed console.error from API client interceptor in api.ts
- Removed console.error from healthCheck method in api.ts
- Removed console.error from BotIntegration.tsx and added proper error handling

**Impact:** Improved security and performance by removing unnecessary console logging.

### 2. **Missing exc_info in Backend Exception Logging**
**Severity:** Medium
**Location:** Backend
**Files Affected:**
- `backend/app/database/weaviate/client.py`
- `backend/app/core/orchestration/queue_manager.py`

**Issue:**
Exception logging without `exc_info=True` makes debugging difficult as stack traces are not captured.

**Fix Applied:**
- Added `exc_info=True` to all exception logging statements in Weaviate client
- Added `exc_info=True` to RabbitMQ connection error logging

**Impact:** Better debugging capabilities with full stack traces in logs.

### 3. **Improved Error Handling in BotIntegration**
**Severity:** Low
**Location:** Frontend
**Files Affected:**
- `frontend/src/components/integration/BotIntegration.tsx`

**Issue:**
Error in `loadIntegrationStatus` was only logged but didn't reset component state, potentially leaving UI in inconsistent state.

**Fix Applied:**
- Added proper state reset (setIsConnected(false), setIntegration(null)) in catch block
- Removed console.error and added descriptive comment

**Impact:** More robust error handling and consistent UI state.
