Describe the Problem

When underlying WebSocket library emits an "error" message this is not correctly propagated to upper levels, thus it creates unhandled rejections.

the issue can be resolved with following;

if (typeof(url) === "string") {
    var _ws = new WebSocket(this.connection.url);
    _ws.on("error", (error) => this.emit("error", error));
    defineReadOnly(this, "_websocket", _ws);
}

Code Snippet

new WebSocketProvider("<a wss url returns 502">");
