Django Channels: Implementing an HTTP endpoint for server-sent events.

In the consumer example that Django Channels provides (attached image) about implementing an HTTP endpoint for Server-sent events (SSE), it leaves me with a doubt: If I implement an endpoint with that consumer, connect to it from a client, and then disconnect, it throws the following error:

And it makes sense since the consumer stays inside the while loop perpetually making an asyncio.sleep(1), and there is no other choice but to kill the function. And if I remove the while loop, the connection closes by itself because the handle function ends.

How could I solve this error? What is the correct way to keep the connection open until the client closes it and avoid that error?


I am attaching the URL of the Django Channels documentation from where I extracted the image. It is located at the bottom of the page:
