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

// 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

// 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>
