AI chat UI non-response failures are typically caused by frontend-backend integration misconfigurations, such as API body format mismatches, missing React dispatch calls, or SSE parsing errors. You should test the backend API first to isolate the issue.

To debug SSE streaming errors in a React chat application, check for SSE chunk parsing errors and verify React state management updates. Ensure missing dispatch calls are fixed and validate that the Vite proxy configuration does not cause streaming timeouts.

Fixing a hidden input bar in a mobile chat layout involves adjusting mobile responsive design configurations in your WhatsApp-style chat UI. This requires debugging CSS layout constraints to ensure the input interface remains visible on mobile screens.

The best way to diagnose file attachment display issues is to check for SQLite base64 truncation in the backend and verify API body format mismatches. Ensure proper handling for uploaded PDF and image attachments in the frontend rendering logic.

Yes, you can use curl to test the backend API endpoint directly, which isolates whether integration bugs originate from the backend or the React frontend. This layer-by-layer diagnosis prevents misdiagnosis of SSE streaming and state management issues.

Vite proxy timeouts during AI response streaming occur when frontend-backend integration configurations drop active connections. Resolving this requires adjusting proxy timeout settings to support continuous SSE streaming without interrupting chat responses.
