Python mod_wsgi write to custom log file instead of apache error_log

I have a Python application which is deployed in production with Apache and mod_wsgi. In my application, I have setup logging as follows:

config file:

log_file = os.path.dirname(os.path.abspath(__file__)) + "/app.log"
log_level = logging.DEBUG

__init__.py file:

root_logger = logging.getLogger()
root_logger.setLevel(config.log_level)

log_format = logging.Formatter("%(asctime)s [%(levelname)s] [%(name)s] %(message)s")

file_handler = logging.FileHandler(config.log_file)
file_handler.setFormatter(log_format)

stream_handler = logging.StreamHandler()
stream_handler.setFormatter(log_format)

root_logger.addHandler(file_handler)
root_logger.addHandler(stream_handler)

This code is executed before the Flask application is created.

All logging that is not an error/exception is correctly logged to this custom file.

However, if an exception is generated while the web server is running, the errors are instead written to Apache's error log instead of the one configured here. How do I configure Python's logging/mod_wsgi/Apache so that everything is written to the log file configured here?

Add your logger to WSGI application loggers, from flask error handling docs:

if not app.debug:
    import logging
    from themodule import TheHandlerYouWant
    file_handler = TheHandlerYouWant(...)
    file_handler.setLevel(logging.WARNING)
    app.logger.addHandler(file_handler)
