Critical bug: Hook called after conditional return
Problem:
- useEffect at line 107 was AFTER early returns (lines 83-102)
- When loading/error states triggered early return
- Hook order changed between renders
- React detected hook order violation
- Component broke with blank screen
Rules of Hooks violation:
❌ Before:
1. All hooks (useState, useQuery, etc.)
2. Early return if loading
3. Early return if error
4. useEffect (line 107) ← WRONG! After conditional returns
✅ After:
1. All hooks including ALL useEffects
2. Early return if loading
3. Early return if error
4. Render
Fix:
- Moved useEffect from line 107 to line 62
- Now before any early returns
- Changed product?.meta to productQ.data?.meta
- Hooks always called in same order
- No conditional hook calls
Result:
✅ Product edit form loads correctly
✅ No React warnings
✅ Follows Rules of Hooks
✅ Consistent hook order every render
