InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable

var connection = new WebSocket('ws://localhost:8080/events/ws/');
                connection.onopen = function () {
                    console.log('Connection open!');
                };
                connection.onclose = function () {
                    console.log('Connection closed');
                };
                connection.onerror = function (error) {
                    console.log('Error detected: ' + error);
                };
                connection.onmessage = function (e) {
                    var server_message = e.data;
                    console.log(server_message);
                };
                // InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable
                connection.send('Hey server, whats up?');

судя по всему, связь с сокетом еще не установлена. Попробуйте connection.send поставить внутрь connection.onopen
