TypeError: Cannot read property 'sendUTF' of null. wrapWs function connection is set to null. #132

TypeError: Cannot read property 'sendUTF' of null. wrapWs function connection is set to null. line 62 stomp-node.js fails.
wrapWS = function(url) { var WebSocketClient, connection, socket, ws; WebSocketClient = require('websocket').client; connection = null; ws = { url: url, send: function(d) { return connection.sendUTF(d);

Example call :

when use stomp over WS var client = Stomp.overWS('ws://localhost:61614/stomp');

Did you solve this

snieguu commented 5 years ago

As a workaround add some sleep after Stomp.overWS to allow establish the connection

It may because you used the client before connection is established, you can try to call client functions inside connectCallBack (second parameter of the connect function) after connection has been established.
