Issues Identified and Fixed

Issue 1: list_plots endpoint error

Problem: Method get_template() didn’t exist in MetaRepository

Fix: Updated endpoint to use direct DataFrame filtering with _as_bool() normalization, matching the approach used in utils.py

Status: ✅ Fixed

Issue 2: Plot file not found

Problem: Generated plot files named {plot}_plot.pdf but API looked for {plot}.pdf

Fix: Updated API endpoint to look for correct filename format matching export_plot() function

Status: ✅ Fixed

Issue 3: Report endpoint “definitely not working”

Result: Report endpoint was actually working perfectly - generated 1.05 MB PDF with all 37 plots

Status: ✅ Working (no fix needed)

Performance Notes

  • Raw data fetch: Fast (uses cache after first request)
  • Data preparation: Fast (uses cache after first request)
  • Single plot generation: Fast (~1-2 seconds)
  • Complete report generation: Moderate (~30-60 seconds for 37 plots + PDF assembly)

Caching Behavior

All endpoints use the existing caching system: - Raw data cached by (snr, ubb) - Prepared data cached by (snr, stype, audience, ubb, ganztag, has_N) - Set use_cache: false to bypass cache

Files Generated During Testing

  1. test_plot_A42.pdf - Single plot (17 KB)
  2. test_report_leh.pdf - Complete report (1.05 MB)
  3. res/0001_2024/plots/ - 37 individual plot PDFs
  4. res/0001_2024/0001_results_leh.pdf - Final report

Conclusion

✅ All API endpoints are fully functional and tested

The FastAPI service layer successfully wraps the pyreporter pipeline with proper error handling, validation, and response formatting. All endpoints work correctly with the Makefile default values.

Ready for production use!
