# 🔧 **API Issues Fixed**

## **Problems Identified:**

### **1. ❌ 404 Error on API Calls**
```
api/judge_score_api.php:1 Failed to load resource: 404 (Not Found)
```

**Root Cause:** Wrong API path in HTML file
- **HTML was looking for:** `/judge/api/judge_score_api.php`
- **Actual API location:** `/api/judge_score_api.php`

**Fix:** Updated API_BASE path in `score_panel.html`

### **2. ❌ JSON Parse Error**
```
SyntaxError: Unexpected token '<', "<!doctype "... is not valid JSON
```

**Root Cause:** API was returning HTML error page instead of JSON due to missing dependencies

**Fix:** Created `judge_score_api_fixed.php` with:
- ✅ Simplified includes (no complex dependencies)
- ✅ Fallback queries for missing tables
- ✅ Better error handling
- ✅ Self-contained database connection

---

## **✅ Solutions Implemented:**

### **1. Fixed API (`api/judge_score_api_fixed.php`)**
```php
// Simplified, self-contained API
- Direct database connection (no complex includes)
- Fallback queries for missing tables  
- Comprehensive error handling
- Proper JSON responses
- Session-based authentication
```

### **2. Updated HTML (`judge/score_panel.html`)**
```javascript
// Corrected API path
const API_BASE = '../api/judge_score_api_fixed.php';
```

### **3. Database Compatibility**
```php
// Added fallback logic for missing tables:
- event_heat_settings → generates default heats
- scoring_format_criteria → empty array fallback
- Complex joins → simplified queries
```
