Unexpected error is logged under INFO log level, not error

[Talkless]

See:

flask-jsonrpc/src/flask_jsonrpc/site.py

Line 390 in 453fc3b

self.logger.info('unexpected error', exc_info=exc)

API client experienced 500, but we did not see anything in apache2 error log.

Bumping log verbosity to DEBUG we started seeing:

[2026-06-18 10:48:07,241] INFO in site: unexpected error "werkzeug.exceptions.BadRequest: 400 Bad Request: pairing_uuid exceeds maximum length of 45 characters" at /...

Why unexpected errors are logged using INFO? I would expect ERROR level.
