CRITICAL FIX: POST /api/contacts/:id/addresses was matching wrong handler Problem: - Routes checked in definition order using startsWith - 'POST /api/contacts' defined before 'POST /api/contacts/' - URL /api/contacts/123/addresses starts with /api/contacts → matched first route - Called "add new contact" handler instead of "add wallet to contact" - Error: "Missing required fields: address, chain, name" Solution: - Sort routes by path length (longest first) before matching - 'POST /api/contacts/' (18 chars) checked before 'POST /api/contacts' (17 chars) - More specific routes now match first This ensures: - POST /api/contacts/123/addresses → matches 'POST /api/contacts/' ✅ - POST /api/contacts → matches 'POST /api/contacts' ✅ User report: "when trying to add a new wallet i get Missing required fields: address, chain, name" Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
