Conversation
Updated backend API endpoints (`ai-chat`, `ai-image`, `google-chat`, `tts`) to fail securely. Exceptions and upstream error bodies are now logged server-side via `console.error`, and generic 'Internal server error' messages are returned to the client to prevent sensitive data leakage. Created `.jules/sentinel.md` journal entry. Co-authored-by: fysp11 <13081700+fysp11@users.noreply.github.com>

🚨 Severity: MEDIUM
💡 Vulnerability: Backend API routes were returning raw upstream results, third-party error bodies, and specific stack trace/exception messages directly to the client when failures occurred.
🎯 Impact: This architectural gap exposed potentially sensitive diagnostic details and infrastructure information to untrusted clients, increasing the attack surface.
🔧 Fix: Implemented a "fail securely" pattern across all backend API endpoints. Server-side logging (
console.error) is now used to record actual errors for debugging, while generic JSON messages like"Internal server error"are returned to the client. Avoided passing through raw data from third-party services in error and response scenarios. Added an entry to.jules/sentinel.mdto document this project-wide learning.✅ Verification: Verified by reviewing API endpoints for generic error responses and running the project's build validation (
pnpm run check).PR created automatically by Jules for task 11720330957250055103 started by @fysp11
