Socket.io Uncaught TypeError: Cannot read property 'apply' of undefined
A particular event doesn’t work in my socket.io programming. 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 by google chrome:
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.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!

The cause of this error is that you're trying to call .emit() via the socket argument of your custom event handlers, which is incorrect usage according to the documentation for socket.io client side API.
Consider revising your client side code as follows by removing the socket argument from your handlers to cause .emit() to be called on the actual socket instance:
socket.on('stuurbedrijfsnaam', function(){ // remove 'socket' here
// cause emit() to be called on actual socket instance
socket.emit('stuurbedrijfsnaam',bedrijfsnaam)
})
The reason socket.emit('phone', 'phone'); in your first html file is that emit() is called on the original socket instance, rather than via a socket argument passed to the event handler, as you are doing in your seconds html file.
Hope that helps!
