Socket.io Uncaught TypeError: Cannot read property 'apply' of undefined

by

A particular event doesn’t work in my program where I am using socket.io. The rest works fine. This is where the problem occurs:

First html file:

 socket.on('connect', () => {socket.emit('phone', 'phone');});

Server file:

io.on('connection', function(socket){ 
   io.on('phone', function(socket, data){ 
      io.emit('stuurbedrijfsnaam', 'stuurbedrijfsnaam'); 
   }); 
});

2nd html file:

socket.on('stuurbedrijfsnaam', function(socket){
    socket.emit('stuurbedrijfsnaam',bedrijfsnaam) 
})

This is the full error given in the console:

index.js:83 Uncaught TypeError: Cannot read property 'apply' of undefined
at r.emit (index.js:83)
at r.onevent (index.js:83)
at r.onpacket (index.js:83)
at r.<anonymous> (index.js:83)
at r.emit (index.js:83)
at r.ondecoded (index.js:83)
at a.<anonymous> (index.js:83)
at a.r.emit (index.js:83)
at a.add (index.js:83)
at r.ondata (index.js:83)
at r.<anonymous> (index.js:83)
at r.emit (index.js:83)
at r.onPacket (index.js:83)
at r.<anonymous> (index.js:83)
at r.emit (index.js:83)
at r.onPacket (index.js:83)
at r.onData (index.js:83)
at WebSocket.ws.onmessage (index.js:83)

It references index.js:83, which is inside a folder made by socket.io itself. There are lines 81, 82 and 83:

Backoff.prototype.setJitter = function(jitter){
    this.jitter = jitter;
    };

Hope I gave enough resources. It would be cool if someone’s help me out. Thanks!

    I find this topic to be really something which I think I would
    never understand. It seems too complex and very broad for me.

    to get the hang of it!

  41. I was curious if you ever considered changing the structure of
    your website? Its very well written; I love what youve got to say.
    But maybe you could a little more in the way of content so people could connect with it better.

    Youve got an awful lot of text for only having one or 2 pictures.
    Maybe you could space it out better?
