logconfig_dict from gunicorn not propagating to UvicornWorker

[mavwolverine]

Following this page https://nuculabs.dev/2021/05/18/fastapi-uvicorn-logging-in-production/:
logging.yaml

version: 1
disable_existing_loggers: false

formatters:
  standard:
    format: "%(asctime)s - %(levelname)s - %(message)s"

handlers:
  console:
    class: logging.StreamHandler
    formatter: standard
    stream: ext://sys.stdout

loggers:
  uvicorn:
    error:
      propagate: true

root:
  level: INFO
  handlers: [console]
  propagate: no

Instead of a yaml file, if I put this config inside gunicorn_conf.py as

worker_class = "lifecycle.worker.BlackSheepUvicornWorker"
logconfig_dict = {
  "version": 1,
  "disable_existing_loggers": False,
  "formatters": {
    "standard": {
      "format": "%(asctime)s - %(levelname)s - %(message)s"
    }
  },
  "handlers": {
    "console": {
      "formatter": "standard",
      "class": "logging.StreamHandler",
      "stream": "ext://sys.stdout"
    }
  },
  "loggers": {
    "uvicorn": {
      "error": {
        "propagate": True
      }
    }
  },
  "root": {
    "level": "INFO",
    "propagate": False,
    "handlers": [
      "console"
    ]
  },
}

uvicorn logs do not show up.

If I add

log_config = {
# above dict
}

in CONFIG_KWARGS, it shows the uvicorn logs in gunicorn logs.

in UvicornWorker > __init__ inside config_kwargs, if you change

"log_config": None,

to

"log_config": self.cfg.logconfig_dict or self.cfg.logconfig,

the logging passes through.

Am I looking at this wrong?

Thanks
