stdout/stderr not working in debug console

[tonila]

launch.json

  {
    "version": "0.2.0",
    "configurations": [
      {
        "type": "node",
        "request": "launch",
        "name": "test",
        "program": "${workspaceRoot}/test.js",
        "console": "internalConsole"
      }
    ]
  }

code

"use strict";
// we are using npm debug module, that uses stdout/stderr to write logs
//process.env.DEBUG = 'server'
//const debug = require('debug')('server');
//debug('debug')
process.stdout.write('stdout\n')
process.stderr.write('error\n')

debug console does not print stdout/stderr
If I change "internalConsole" to "integratedTerminal" or run app from terminal, stdout/stderr works fine
