builtins.RuntimeWarning: 从未等待协程 'SyncToAsync.__call__'
builtins.RuntimeWarning: coroutine 'SyncToAsync.__call__' was never awaited
在调试丢弃的 channel_layer 消息问题时，我调高了 daphne verbosity 并且偶尔会在日志文件中看到如下所示的警告。真正的问题还是我可以忽略它们？

是的，警告是真正的问题，但我的错误代码。
我在我的 WebsocketConsumer 派生 类 中缺少一些 async_to_sync 包装器，特别是用 @database_sync_to_async.
装饰的 channels.auth.get_user()
