Having Trouble sending long message Python Logs From Google Cloud Functions Out Of Google Cloud Platform

Question

I was wondering whether cloud functions has restrictions to export logging from python out of Google Cloud Platform for long messages (over 1500 characters).

The below are multiple examples from Papertrail on how to send log messages from Python, but the one I tried is below which worked sending messages to Papertrail on Google Compute Engine, but did not work on Google Cloud Functions. Google Cloud Function instead logs them in Google Cloud Operation Logging Service.

import logging
import socket
from logging.handlers import SysLogHandler

class ContextFilter(logging.Filter):
    hostname = socket.gethostname()

    def filter(self, record):
        record.hostname = ContextFilter.hostname
        return True

syslog = SysLogHandler(address=('logsN.papertrailapp.com', XXXXX))
syslog.addFilter(ContextFilter())

format = '%(asctime)s %(hostname)s YOUR_APP: %(message)s'
formatter = logging.Formatter(format, datefmt='%b %d %H:%M:%S')
syslog.setFormatter(formatter)

logger = logging.getLogger()
logger.addHandler(syslog)
logger.setLevel(logging.INFO)

logger.info("This is a message")

In particular, it seems that for the above code, the address I placed on the handler does not work in Google Cloud Function if the message I pass is too long.

syslog = SysLogHandler(address=('logsN.papertrailapp.com', XXXXX))

Is this normal or my cloud function has some issues? Is there a way I can pass an address in my python logging within Google Cloud Functions that can be compatible for long messages?
