No listeners found for event: "event name"

Hi,

Thanks for this great contribution and this amazing framework.
Recently I noticed one problem with defining requester and responder in a single file.
Consider file A includes:

const cote = require('cote');
const responder = new cote.Responder({name: "testresponder"});
const requester = new cote.Requester({name: "testrequester"});

requester.send({type: 'call'}, (res) => {
    console.log(res);
});

and file B includes:

const cote = require('cote');
const responder = new cote.Responder({name: "callresponder"});

responder.on('call', (req, cb) => {
    cb("test");
});

I first start the file B which is the responder and then I run the file A. the console log is:
testresponder > No listeners found for event: call
But when I delete the responder initiation in file A, it will work just fine. However, defining keys will solve the problem, but I don't know why this won't work without keys.

I was hoping that the error message would be clear: testresponder on file A really doesn't have an event listener. if you do

responder.on('call', (req, cb) => {
    cb("test");
});

on file A as well, it will work, and load balance between the one in file A and the one in file B.

Hmmm ... I don't get it why should I have the responder in my A file? Consider each file as an independent microservice, I want A to ask something from B, no more. In this case shouldn't the framework discover B?
If I'm gonna have two responders, which one gonna answer my A requester?

I'm sorry I'm a bit confused.

That's totally fine, then you shouldn't have a responder in file A. :) you got that error because you had a responder in A that can't handle the message call.

I get it now! it seems I shouldn't initiate a responder when I have no listener on it.

Thanks for your help.

I get this error too:

this is my responder:

const cote = require('cote');
var auth_consumer = new cote.Responder({ name: 'auth_service' });

auth_consumer.on('generate-token', async (req, cb) => {
      cb(null, {message: "ok", token: createTokens(req.device, req.exp), status:200})
  });

I am getting this in One in between two requests :

socket-service > No listeners found for event: generate-token
