Environment:

- Service: Django application on Railway

- Runtime: Python 3.11

- Web Server: Gunicorn

- Branch: development_20250603

Issue Description:

Our Django application is running successfully on Railway, but JSON print statements are not appearing in the Railway logs despite the

application functioning correctly.

What We've Tried:

1. Migrated from Python logging to direct print statements following Railway's JSON logging documentation:

# Info/Debug to stdout

print(json.dumps({"message": "...", "level": "info", ...}))

sys.stdout.flush()

# Warning/Error to stderr

print(json.dumps({"message": "...", "level": "error", ...}), file=sys.stderr)

sys.stderr.flush()

2. Disabled Django LOGGING configuration to prevent interference:

LOGGING = {

'version': 1,

'disable_existing_loggers': False,

'handlers': {'null': {'class': 'logging.NullHandler'}},

'root': {'handlers': ['null']},

}

3. Added explicit flush calls to ensure immediate output

Current Behavior:

- App startup logs appear correctly (JSON format working)

- Initial page load logs appear (user authentication, API initialization)

- AJAX endpoint logs don't appear (api_loading_status, item analysis, etc.)

- User action logs missing (button clicks, form submissions)

Example of Last Visible Log:

{

"message": "Generated auth URL: https://auth.ebay.com/...",

"level": "info",

"user_id": 1,

"username": "ebay_administrator"

}

Key Observation:

The application works perfectly - all user actions complete successfully, databases update correctly, and UI responds properly. The

issue is purely that our JSON print statements aren't reaching Railway's log collector after the initial page load.

Question:

Does Railway's log collection have any limitations with:

- Gunicorn worker processes and stdout/stderr capture?

- AJAX request logging vs initial page load logging?

- Print statement buffering in Django applications?

- JSON format requirements beyond what's documented?

Expected Result: All JSON print statements should appear in Railway logs

Actual Result: Only initial startup and page load logs appear

Any guidance on Railway-specific logging requirements for Django applications would be greatly appreciated.
