Пытаюсь запустить uvicorn на сервере виртуального хостинга (Linux Debian):
uvicorn etebase_server.asgi:application --port 8000 --host 0.0.0.0 --lifespan on
uvicorn запускается, может обработать пару HTTP GET, но затем отключается примерно через 30 секунд. Вот сообщение об ошибке:
INFO: Started server process [125907]
INFO: Waiting for application startup.
INFO: Application startup complete.
INFO: Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)
INFO: Shutting down
INFO: Waiting for application shutdown.
ERROR: Exception in 'lifespan' protocol

Любая идея о AttributeError: 'RedisWrapper' object has no attribute 'redis' ???
