How to configure rsyslog to use the centralized log with Python

The rsyslog with elk runs well in a docker of localhost.

I could see the logs in Kibana with commands below:

logger -n localhost 'log message from test99'
logger -n localhost 'log message from test99'
logger -n 10.211.55.12 'log message from test99'
logger -n 10.211.55.12 'log message from test99234234'

The questions here, I want to use rsyslog with my Python application. The demo code shows below with the same configuration of rsyslog.

But I couldn't get anything from the Python application. So what's wrong with my configuration or code?

10.211.55.12 is the IP address of my localhost

log_test.py

import logging
import logging.handlers

logger = logging.getLogger('myLogger')
logger.setLevel(logging.INFO)

# Add handler to the logger
handler = logging.handlers.SysLogHandler('/dev/log')

# Add formatter to the handler
formatter = logging.Formatter('Python: { "loggerName":"%(name)s", "asciTime":"%(asctime)s", "pathName":"%(pathname)s", "logRecordCreationTime":"%(created)f", "functionName":"%(funcName)s", "levelNo":"%(levelno)s", "lineNo":"%(lineno)d", "time":"%(msecs)d", "levelName":"%(levelname)s", "message":"%(message)s"}')

handler.formatter = formatter
logger.addHandler(handler)
for _ in range(100):
    logger.info("Test Message")
