Lovable Troubleshooting

Connection & Setup

Problem	Tell Lovable
Nothing works — all API calls fail or Edge Functions return 404	Connect Supabase, deploy all Edge Functions (locations-search, hotels-search, hotel-static-content, rooms-and-rates, bookings-price-check, bookings-create, bookings-get, bookings-saved, bookings-saved-one), and run the bookings migration SQL from the prompt.
Auth or hotel API fails with 401 / "Travclan auth failed"	Set these in Lovable Cloud Secrets: `TRAVCLAN_API_KEY, TRAVCLAN_USER_ID, TRAVCLAN_MERCHANT_ID, TRAVCLAN_AUTH_URL, TRAVCLAN_SEARCH_API_URL, TRAVCLAN_HOTEL_HELPER_HOST, TRAVCLAN_SOURCE=website`. Redeploy Edge Functions after updating secrets.
APIs work in sandbox but fail after go-live	Credentials and URLs must match the same environment. Update all three URL secrets from sandbox to production (trav-auth, hotel-volt-api, hotel-api without -sandbox) and use production API keys. Redeploy Edge Functions.
My Bookings page is empty even after booking	Ensure the bookings table exists. bookings-create must always insert a row on every book attempt. Check the Supabase table directly.

Edge Functions & Errors

Problem	Tell Lovable
CORS errors in browser console when calling Edge Functions	All Edge Functions must set CORS headers for the Lovable frontend origin on every response, including errors.

Quick Mega-Fix

If the build has drifted off-spec in several places at once, paste this single message into Lovable instead of fixing things one at a time:

Re-align with the full prompt: Supabase Edge Functions proxy all Travclan calls; secrets in Supabase not frontend; bookings table + RLS; parse results.data for hotels and results.options for rooms; parseEdgeFunctionError for rooms rates; UI Error Rules (no Travclan/Volt in UI); src/config/brand.ts for theming; header tabs Hotels/Flight/Packages (only Hotels clickable); sandbox URLs in secrets until production go-live.
