In python3.10 and above, it does not work after configuring it through dictConfig.

Here is an example:

...

LOGGING_DICT = {
    "version": 1,
    "formatters": {
        "colored": {
            "format": "%(log_color)s%(levelname)-8s%(reset)s %(blue)s%(message)s",
            "datefmt": "%Y-%m-%d %H:%M:%S",
            "()": "colorlog.ColoredFormatter",
        },
    },
    "handlers": {
        "colored": {
            "level": "INFO",
            "class": "colorlog.StreamHandler",
            "formatter": "colored",
        },
    },
    "loggers": {
        "example": {
            "lever": "INFO",
            "handlers": ["colored"],
            "propagate": True,
        },
    },
}

logging.config.dictConfig(LOGGING_DICT)

logger = logging.getLogger("example")
logger.info("This is an info message")

There is no printed result. What is the reason for this? Is there an effective solution?

Python Version: 3.10.12
colorlog version: 6.9.0

I regret to inform you this is a simple typo:

     "loggers": {
         "example": {
-            "lever": "INFO",
+            "level": "INFO",
             "handlers": ["colored"],
             "propagate": True,
         },
     },

OK, that was my problem, thanks for replying.
