From a16787da7ee02f5f9a1a8599b3f4c6235dd6c623 Mon Sep 17 00:00:00 2001 From: Harkirat Date: Wed, 5 Aug 2026 14:44:22 +0530 Subject: [PATCH 1/4] fix(notion): auth token + caching to survive Cloudflare 403 blocks Notion's unofficial /api/v3 endpoints (loadPageChunk) are hard-blocked by Cloudflare with a 403 "Attention Required" page when called from datacenter egress IPs, which was 500'ing every track/problem page in production. - Add getNotionClient() that authenticates with NOTION_TOKEN_V2 / NOTION_ACTIVE_USER so requests aren't challenged; reuse a singleton. - Cache recordMaps (10m TTL) with a never-expiring stale fallback so a transient Notion/Cloudflare failure degrades to slightly-stale content instead of a 500, and to cut the request volume keeping our IP flagged. - Retry getPage/getBlocks with backoff. - Guard NotionRenderer against an empty/missing recordMap. - Document the new env vars in .env.example and turbo.json.

The block is IP-reputation based and re-triggers under request bursts, so add a global concurrency cap + min-gap throttle and back off harder on 403s; combined with the existing 30m cache + stale fallback this keeps request volume low enough to stay unblocked.
