# Hotfix Deployment - February 12, 2026

## Issues Fixed

### Issue 1: Internal Server Error on Contact Creation ❌ → ✅
**Problem**: Foreign key constraint violation when creating contacts  
**Root Cause**: Form was sending empty string `""` for `parentId` field instead of `undefined`  
**Fix**: Updated ContactForm to:
- Use `undefined` for optional fields instead of empty strings
- Clean data before submission to remove empty optional fields
- Properly handle `parentId` field

**File Modified**: `frontend/src/components/contacts/ContactForm.tsx`

### Issue 2: Category Checkboxes Not Clickable ❌ → ✅
**Problem**: Checkboxes in category selector didn't respond to clicks  
**Root Cause**: Checkbox was a non-interactive `div` element  
**Fix**: Changed checkbox from `div` to `button` with proper click handler

**File Modified**: `frontend/src/components/contacts/CategorySelector.tsx`

## Fixed Code Changes

### ContactForm.tsx - Data Cleaning
```typescript
// Before (BROKEN)
parentId: contact?.parent?.id || '',  // Empty string causes DB error

// After (FIXED)
parentId: contact?.parent?.id,  // undefined if not present

// Added data cleaning before submit
const cleanData = Object.entries({ ...formData, rating }).reduce((acc, [key, value]) => {
  if (value !== '' || ['type', 'name', 'source', 'country'].includes(key)) {
    acc[key] = value
  }
  return acc
}, {} as any)
```

### CategorySelector.tsx - Interactive Checkbox
```typescript
// Before (BROKEN)
<div className="...">  {/* Not clickable */}
  {isSelected && <Check />}
</div>

// After (FIXED)
<button
  type="button"
  onClick={(e) => {
    e.stopPropagation()
    toggleSelect(category.id)
  }}
  className="... cursor-pointer"
>
  {isSelected && <Check />}
</button>
```
