Problem was in my config file: your library doesn't support the formatter:

log_config = {
    "version": 1,
    "disable_existing_loggers": False,
    "formatters": {
        'simple': {
            'format': '%(asctime)s %(name)-12s %(levelname)-8s %(message)s'
        }
    },
    "handlers": {
        "telegram": {
            "class": "python_telegram_logger.Handler",
            "token": Config.TALEGRAM_TOKEN,
            "chat_ids": [Config.TELEGRAM_MONITORING_CHAT_ID],
            # "formatter": "simple",
            "level": "WARNING",
        },
         "console": {
            "class": "logging.StreamHandler",
            "formatter": "simple",
            "level": "INFO",
        },
    },
    "root": {
        "handlers": ["telegram", "console"],
        "level": "INFO",
    }
}
