# Auto Import System - Fixes Applied

## Issues Fixed

### 1. **"Failed to load import statistics" Error**

**Problem:** Error terjadi saat mengklik tombol "Import Stats" karena:
- Method `getImportStats()` mengembalikan `null` ketika tabel tidak ada
- JavaScript tidak menangani response dengan baik
- Tidak ada error handling yang proper

**Solution:**
- ✅ Perbaiki `DataImportService::getImportStats()` untuk selalu mengembalikan array
- ✅ Tambahkan proper error handling di controller
- ✅ Perbaiki JavaScript untuk menangani berbagai response
- ✅ Tambahkan logging untuk debugging

### 2. **Improved Error Handling**

**Changes Made:**

#### DataImportService.php
```php
public function getImportStats(ApiSource $source)
{
    try {
        $tableName = $source->table_name;
        
        if (!Schema::hasTable($tableName)) {
            return [
                'total_records' => 0,
                'today_records' => 0,
                'last_import' => $source->last_fetched_at,
                'next_import' => $this->getNextImportTime($source),
                'schedule_type' => $source->schedule_type,
                'schedule_frequency' => $source->schedule_frequency,
                'table_exists' => false,
                'message' => 'Table "' . $tableName . '" does not exist'
            ];
        }
        // ... rest of the method
    } catch (\Exception $e) {
        Log::error('Error getting import stats for source ' . $source->id . ': ' . $e->getMessage());
        return [
            // ... error response
        ];
    }
}
```

#### ApiSourceController.php
```php
public function importStats(ApiSource $apiSource)
{
    try {
        $importService = new DataImportService();
        $stats = $importService->getImportStats($apiSource);

        // Handle case when stats is null (table doesn't exist)
        if ($stats === null) {
            $stats = [
                'total_records' => 0,
                'today_records' => 0,
                'last_import' => $apiSource->last_fetched_at,
                'next_import' => null,
                'schedule_type' => $apiSource->schedule_type,
                'schedule_frequency' => $apiSource->schedule_frequency,
                'table_exists' => false,
                'message' => 'Table "' . $apiSource->table_name . '" does not exist'
            ];
        } else {
            $stats['table_exists'] = true;
            $stats['message'] = 'Statistics loaded successfully';
        }

        // ... rest of the method
    } catch (\Exception $e) {
        Log::error('Import stats error for source ' . $apiSource->id . ': ' . $e->getMessage());
        // ... error handling
    }
}
```

#### JavaScript (data.blade.php)
```javascript
function showImportStats(id) {
    // ... existing code ...
    
    .then(response => {
        if (!response.ok) {
            throw new Error(`HTTP ${response.status}: ${response.statusText}`);
        }
        return response.json();
    })
    .then(data => {
        if (data.success && data.stats) {
            const stats = data.stats;
            let message = `Import Statistics:\n\n`;
            
            // Add table status
            if (stats.table_exists === false) {
                message += `⚠️  ${stats.message}\n\n`;
            }
            
            // ... rest of the display logic
        } else {
            const errorMessage = data.message || 'Failed to load import statistics';
            // ... error display
        }
    })
    .catch(error => {
        console.error('Import stats error:', error);
        // ... error handling
    });
}
```
