Client retries indefinitely if server resolver throws an error

[alhambra1]

Hi,

Using socket-apollo-link with an Apollo client, if the Absinthe GraphQL resolver on our server throws an error, our client and server seem to get stuck in a cycle where the client action is not aborted but keeps retrying and failing. The raw websocket cycle looks something like:

client: send action
server: ["9","9","__absinthe__:control","phx_error",{}]
client: ["21","21","__absinthe__:control","phx_join",{}]
server: ["21","21","__absinthe__:control","phx_reply",{"response":{},"status":"ok"}]
client: resubscribe to subscriptions
back to top...

How would you recommend handling this on the client? Ideally, the client should have a way to associate a server crash with a permanent error. Is there an exposed method we can use to abort the action (aside from disconnecting the socket)?

@alhambra1 if it's still actual, this is how I handle this issue:

interface IUsePhxErrorHandler {
  socket?: PhoenixSocket;
  absintheSocket?: AbsintheSocket;
  skip?: boolean;
}
export const usePhxErrorHandler = ({ socket, absintheSocket, skip }: IUsePhxErrorHandler) => {
  useEffect(() => {
    if (!skip && socket && absintheSocket) {
      socket.onMessage(({ event, topic }) => {
        if (event === "phx_error" && topic === "__absinthe__:control") {
          absintheSocket.notifiers = absintheSocket.notifiers.reduce<Notifier[]>((notifiers, notifier) => {
            if (notifier.operationType === "subscription") {
              notifiers.push(notifier);
            } else {
              cancelNotifier(absintheSocket, notifier);
            }
            return notifiers;
          }, []);

          // Then you could notify user about the error, send it to Sentry, etc.
        }
      });
    }
  }, [socket, absintheSocket, skip]);
};
