    traceback.print_stack(file=self.stderr)

my code:

from my_package_path import MyLogger

my_config = {
    'version': 1,
    "disable_existing_loggers": False,
    'formatters': {
         "exp_formatter": {"()": 'path.to.my.formatter', "format": "EXPERIMENTAL log formatter - %(name)s - %(levelname)s - %(message)s"},
        
    },
    'handlers': {
        'root_logger_handler': {
            'class': 'logging.StreamHandler',
            'level': 'INFO',
            'formatter': "exp_formatter"
        }
    },
     'loggers': {
         '': {
            'level': 'INFO',
            'handlers': ['root_logger_handler']
         },
     }
}

This configuration is added to Faust logging_config and later i call app.main(), where i get the error. I can also tell that when im trying to serialize the configuration using json.dumps(my_config) im getting an error saying that the object is not serlizable, so it might be connected as well.

Help would be appreciated!
