Why is BeautifulSoup related to 'Task exception was never retrieved'? There are similar services you can use to retrieve it but you're not sure if they will be accessible at runtime. When a coroutine is wrapped into a Task with functions like eate_task() the coroutine is automatically scheduled to run soon— Coroutines and Tasks. Ideally we'd give our non-blocking calls a timeout, after which we just send our complex response without the IP attribute.
