Fix swallowed query-parse errors in request handler

The logging call passed the exception as a positional argument with no
%s placeholder in the format string:

    LOGGER.error("Error parsing query: ", e)

Python's logging applies msg % args, which raised TypeError (not all
arguments converted during string formatting) inside logging.handleError.
The logging framework swallows that secondary error, so neither the
intended message nor the exception was ever recorded.

Use an f-string so the exception is actually rendered and logged.
