URL: https://github.com/apache/superset/pull/37345#issuecomment-3781559555
## **Sequence Diagram**
The PR adds a pipeline that extracts custom_errors from database engine spec
files and merges them into the generated databases documentation; the frontend
then renders a "Troubleshooting" section from that data. The diagram shows the
core success path from extraction to rendering.

participant DocGen as generate-database-docs.mjs
participant Extractor as extract_custom_errors.py
participant Specs as db_engine_specs (Python)
participant Data as databases.json
participant Frontend as DatabasePage.tsx
DocGen->>Extractor: Run extractor script (python)
Extractor->>Specs: Parse engine spec files for custom_errors
Specs-->>Extractor: Return extracted custom_errors JSON
Extractor-->>DocGen: Print JSON (stdout)
DocGen->>Data: Merge custom_errors into per-database docs
Frontend->>Data: Load generated databases.json
Frontend->>Frontend: RenderTroubleshooting() using docs.custom_errors
```
