Hi, I tried to reproduce your problem: import ReconnectingWebsocket from "reconnecting-websocket";
import WebSocket from "ws";
const rws = new ReconnectingWebsocket("ws://lokalhost:8080", undefined, {WebSocket});
rws.addEventListener("error", () => {
console.log("error");
});This works as expected. Can you please send a snippet where your issue is reproduced? More details about the library version, environment, etc, would be helpful |

@lagden Thanks for reporting! Event handlers were not supporting objects with handleEvent |

I'm running into the following scenario, I'm providing incorrect URL on perpouse with 0 retry option.
const options = {
connectionTimeout: 500,
maxRetries: 0,
debug: true
};
const rws = new ReconnectingWebSocket('ws://**lokalhost**:8080', [], options);Registering on error event listener:
Looks like any registered listener is removed on connection error and never get called from the internal _handleError
getting this error TypeError: this._listeners.error is undefined
Any recommendations how to handle initial connection errors ?
