Django logger only logging to console from celery worker process

I have a following logging config:

"root": {
    "level": "ERROR",
    "handlers": ["console", "server_file"],
},
"handlers": {
    "celery_file": {
        "class": "logging.handlers.RotatingFileHandler",
        "level": "DEBUG",
        "filename": os.path.join(ROOT_LOGS_DIR, "celery", "celery.log"),
        "formatter": "standard",
        "maxBytes": 1024 * 1024 * 50,  # 50 MB
        "backupCount": 30,
    },
    "server_file": {
        "class": "logging.handlers.RotatingFileHandler",
        "level": "DEBUG",
        "filename": os.path.join(ROOT_LOGS_DIR, "server.log"),
        "formatter": "standard",
        "maxBytes": 1024 * 1024 * 50,  # 50 MB
        "backupCount": 30,
    },
"loggers": {
    # '': {'handlers': ["root"], "level": "DEBUG", "propagate": True, },
    'django': {'handlers': ['django'], 'level': 'DEBUG', 'propagate': False, },        
    "celery": {
        "handlers": ["celery_file"],
        "level": "INFO",
        "propagate": True,
    },

From celery task,

log = logging.getLogger("celery.inbound_outbound_jobs")
log.error("Hello, World!") # this won't be written to files. Only Console.

I run this task using celery-beat and worker.

celery -A log_project beat --loglevel=info
celery -A log_project worker --loglevel=info

But this is not writing logs to server.log and celery.log.

Only console logging is happening.

When running this task directly from django server and not as celery worker process, this is working in all celery.log, server.log and console.

Can anyone help understand this?
