Please upgrade ASAP. With the following environment variables: env_nested_delimiter can be configured via the Config class as shown above, or via the @es3n1n, @jokull, @JonasKs, @Rehket, @corleyma, @daddycocoaman, @hardbyte, @datarootsio, @jodal, @aminalaee, @rafsaf, If you're looking for a programmatic equivalent of the uvicorn command line interface, use uvicorn.run(): For more control over configuration and server lifecycle, use uvicorn.Config and uvicorn.Server: If you'd like to run Uvicorn from an already running async environment, use uvicorn.Server.serve() instead: Gunicorn is a mature, fully featured server and process manager. See documentation for more details. config setting, then use an env variable with a name pointing to the nested module fields. For more information, see the deployment documentation.
