<!-- Answer --> I found a similar unsolved discussion that might be relevant to your issue: [Additional StreamHandler in the DefaultLoggingConfigurator causes duplicate logs](https://github.com/apache/superset/discussions/23963) <sup>[[1]](https://github.com/apache/superset/discussions/23963)</sup>. To address the issue of Apache Superset version 4.0.2 writing logs to `stderr` in production mode, you can modify the logging configuration to redirect logs to `stdout`. Here is an example of how you can achieve this by subclassing `DefaultLoggingConfigurator`: ```python import logging import sys from flask import Config from superset.utils.logging_configurator import DefaultLoggingConfigurator class StdoutLoggingConfigurator(DefaultLoggingConfigurator): def configure_logging(self, app_config: Config, debug_mode: bool) -> None: # Call the parent method to set up the initial configuration super().configure_logging(app_config, debug_mode) # Get the 'superset' logger superset_logger = logging.getLogger("superset") # Remove all existing handlers for handler in superset_logger.handlers: superset_logger.removeHandler(handler) # Add a new handler that writes to stdout handler = logging.StreamHandler(sys.stdout) handler.setFormatter(logging.Formatter(app_config["LOG_FORMAT"])) superset_logger.addHandler(handler) # Set the custom logging configurator LOGGING_CONFIGURATOR = StdoutLoggingConfigurator() # Apply the basic configuration to redirect logs to stdout logging.basicConfig( stream=sys.stdout, format="%(asctime)s:%(levelname)s:%(name)s:%(message)s", force=True, ) ``` This code will ensure that logs are written to `stdout` instead of `stderr`, preventing the misclassification of log messages in cloud environments like Google Kubernetes Engine (GKE) <sup>[[2]](https://github.com/apache/superset/blob/master/superset/utils/logging_configurator.py)</sup>. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* -- This is an automated message from the Apache Git Service.
