CI4 Response Flow Fix | Generated by AI

Home 2026.04

Done. Here’s what I fixed:

The core issue was a CI3→CI4 response flow mismatch. In CI3, succeed()/failure() would echo JSON and the framework captured it. In CI4, gatherOutput() overwrites the response body with its own output buffer — so calling $this->response->setJSON() without actually putting content into the buffer meant zero bytes on every response.

Fixes applied:

  1. BaseController::responseResult() & responseJSON() — Added echo $response->getBody() so the JSON goes into CI4’s output buffer. This is the pragmatic fix since hundreds of controller call sites use succeed()/failure() without return.

  2. Lives::attended() — Added null session guard. Was crashing on $curUser->userId when no auth session existed.

  3. Missing KEY_IS_SCANNED constant — Added to Constants.php.

30/30 routes → HTTP 200 with proper JSON bodies ✅

Remaining items: real login session testing, payment stubs, DB migrations. Want me to tackle any of those next?
