Fix undefined variable crashes when accessing property 'length' on undefined: - "can't access property 'length', e is undefined" CHANGES: 1. Election detail page ([id]/page.tsx): - Ensure candidates array exists when fetching election data - Default to empty array if API returns undefined candidates 2. Active elections list page (active/page.tsx): - Validate API response is an array before processing - Ensure each election has candidates array with fallback 3. Blockchain visualizer (blockchain-visualizer.tsx): - Add optional chaining check before accessing data.blocks - Prevent crashes when data prop is undefined All changes follow defensive programming practices: - No more direct property access without null checks - Array fallbacks ensure predictable behavior - Optional chaining used consistently This fixes the error that occurred when navigating to election pages. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
