Unknown-path WS probes (e.g. /waapi) generate three INFO lines from
uvicorn.access + uvicorn.error on every attempt. Install a logging.Filter
on both loggers at startup to drop:
- access log entries: "WebSocket <path>" 403
- error log entries: "connection rejected ..." / "connection closed"
These are handled gracefully by _SPAStaticFiles; the logs add no value.
