Best way to handle WebSocket errors in Django Channels without closing the connection?

[damnNepali]

Hey everyone 👋
I’m building a WebSocket-based feature using Django Channels, and I’m a bit confused about best practices for error handling.
Let’s say I’m processing messages in my consumer — if something fails (like invalid data), what’s the cleanest way to send the error back to the client without closing the WebSocket?
I tried using try/except and sending an "error" message manually, but I’m not sure if that’s considered good practice.
Also, how do you properly handle exceptions during connection/authentication (so it closes gracefully)?
Would love to hear how others are doing it 🙏

Hey! 👋
You’re actually on the right track.
For runtime errors (inside receive_json), catching exceptions and sending a structured "error" message back to the client is totally fine — that’s how most production apps handle it.

async def receive_json(self, content):
try:
# your logic here
await self.send_json({"type": "success", "data": "ok"})
except Exception as e:
await self.send_json({"type": "error", "message": str(e)})
