Cannot call handle_open to handle JWT expiration

If you're connecting via anycable-go, you should enable JWT identification

Oh, I didn't know that.

If you're not using AnyCable JWT feature, and using a custom token-based auth instead, you should use the #connect method, right.

In our case, we're using a custom token-based auth.
It worked perfectly with your code!

I could understand very clearly.
Thanks @palkan !

I expect handle_open method is called when the websocket connection establishes.

The #handle_open is only called when you're connecting via Action Cable server.

If you're connecting via anycable-go, you should enable JWT identification (e.g., anycable-go --jwt_id_key=<some key>). In this case no RPC is performed at all, anycable-go authenticate the connection on its end.

If you're not using AnyCable JWT feature, and using a custom token-based auth instead, you should use the #connect method, right. The only change required is to add reject_unauthorized_connection after the #close call:

def connect
  self.current_user = find_verified_user
rescue VerificationFailed
  logger.error 'An expired JWT token was rejected'
  close(reason: 'token_expired', reconnect: false) if anycabled? || websocket.alive?
  reject_unauthorized_connection
end

Note that I added if anycabled? || websocket.alive?. This is to make this code backward-compatible with Action Cable server in case you use it in other environments (and don't want it to raise exception when tryin to close non-alive socket).
