I am trying to use python logging module to output messages to a file, I found some configurations online and customized it to what I need but it isn't printing what I want it to print. No DEBUG level messages are appearing in the file handler with DEBUG level.

I am using this JSON configuration for the logger:

{  "version": 1,  "formatters": {    "simple": {      "format": "%(asctime)s : %(levelname)-8s - %(name)s : %(message)s",      "datefmt": "%Y-%m-%d %H:%M:%S"    }  },  "handlers": {    "file_handler": {      "class": "logging.handlers.RotatingFileHandler",      "level": "DEBUG",      "formatter": "simple",      "filename": "info.log",      "maxBytes": 1E6,      "backupCount": 5,      "encoding": "utf8"    },    "error_file_handler": {      "class": "logging.handlers.RotatingFileHandler",      "level": "ERROR",      "formatter": "simple",      "filename": "errors.log",      "maxBytes": 1E6,      "backupCount": 5,      "encoding": "utf8"    }  },  "root": {    "level": "INFO", # EDIT - change this to DEBUG to fix    "handlers": ["file_handler", "error_file_handler"]  }}

And I execute this code:

import loggingimport logging.config as lconfigimport jsonwith open('logger.json', 'rt') as f:    config = json.load(f)lconfig.dictConfig(config)logger = logging.getLogger(__name__)logger.info('info')logger.warning('warning')logger.debug('debug')logger.error('error')logger.critical('critical')

The problem here is the fileinfo.log does not have the debug line, the output is this:

2020-01-03 15:32:23 : INFO     - __main__ : info2020-01-03 15:32:23 : WARNING  - __main__ : warning2020-01-03 15:32:23 : ERROR    - __main__ : error2020-01-03 15:32:23 : CRITICAL - __main__ : critical

What should I do to fix this and print debug messages to theinfo.log file?
