Sketch AI Provider Debug

Sketch AI Provider Debug

Overview

Provide a consistent debug flow for image generation failures across OpenAI and Gemini providers without leaking secrets.

Workflow

1) Verify configuration

• Confirm OPENAI_API_KEY / GEMINI_API_KEY exist.
• Confirm DEFAULT_PROVIDER, OPENAI_IMAGE_MODEL, GEMINI_IMAGE_MODEL match supported models.
• Use /api/health to confirm defaults.

2) Reproduce with a controlled request

• Use a tiny PNG and short prompt.
• Use curl to hit /api/convert (multipart form data).
• Keep logs visible (server + client).

3) Interpret common failures

• 500: provider error, missing key, quota, or model mismatch.
• 400: invalid image type, size, or prompt.
• Timeout: provider latency or host timeout config.

4) Fix or adjust

• Swap to a known-good model.
• Reduce image size or prompt complexity.
• Confirm provider SDK versions align with supported endpoints.

5) Report safely

• Do not log API keys or raw image bytes.
• Summarize error codes and timing only.
