remoteStack bug

[StarpTech]

Question: Why I have two error objects in the remoteStack which point to the same error in the service c ?

I create following scenario:

service-a

const mu = require('mu')({
  dev: process.NODE_ENV !== 'production'
})
const tcp = require('mu-tcp')

// define routing:

mu.inbound({
  role: 'some'
}, tcp.server({
  port: 3000,
  host: '127.0.0.1'
}))

mu.outbound({
  role: 'other'
}, tcp.client({
  port: 3001,
  host: '127.0.0.1'
}))

// define patterns:

mu.define({
  role: 'some',
  cmd: 'sub'
}, function (args, cb) {

  mu.dispatch({
    role: 'other',
    cmd: 'sub',
    a: 1,
    b: 2
  }, function (err, result) {

    if (err) {
      return cb(err);
    }

    cb(null, result);
  })
})

service b

const mu = require('mu')({dev: process.NODE_ENV !== 'production'})
const tcp = require('mu-tcp')

// define routing:

mu.outbound({role: 'some'}, tcp.client({port: 3000, host: '127.0.0.1'}))

// define patterns:

mu.dispatch({ role: 'some', cmd: 'sub', a: 1, b: 2 }, function (err, result) {
  
  console.log(JSON.stringify(err))
})

service c

const mu = require('mu')({
  dev: process.NODE_ENV !== 'production'
})
const tcp = require('mu-tcp')

// define routing:

mu.inbound({
  role: 'other'
}, tcp.server({
  port: 3001,
  host: '127.0.0.1'
}))

// define patterns:

mu.define({
  role: 'other',
  cmd: 'sub'
}, function (args, cb) {
  
  cb(mu.error.wrapRemote(mu.error('invalid'), 1, 500, { msg: 'jesus' }))
  
})

Steps to reproduce

1. Start service c
2. Start service a
3. Start service b

I got following error payload

something looks broken here - requires investigation
