Getting "TypeError: file argument must be a non-empty string" when Cordova Build task

I am running a Cordova Build task in VSTS that builds for iOS the signing files attached:

enter image description here

However, when I execute the task, I get the following error:

TypeError: "file" argument must be a non-empty string
    at normalizeSpawnArguments (child_process.js:383:11)
    at spawnSync (child_process.js:519:38)

    at _combinedTickCallback (internal/process/next_tick.js:131:7)

Tracing back through the code of child_process, I am pretty confident this error is occurring because the file argument is not a string. Below is a snippet of the call chain:

xcode-util-task.js

var spawnResult = spawn(createKeychain, createKeychainArgs, { stdio: "inherit" });

child_process.js

function spawnSync() {
  var opts = normalizeSpawnArguments.apply(null, arguments);

...

function normalizeSpawnArguments(file, args, options) {
  if (typeof file !== 'string' || file.length === 0)
    throw new TypeError('"file" argument must be a non-empty string');

Indeed that does appear to be the case. The first argument of spawn(), createKeychain, is an object and not a string. I get the following when I print the object out:

{ [String: '/bin/bash']
  stdout: '/bin/bash',
  stderr: null,
  code: 0,
  cat: [Function: bound ],
  exec: [Function: bound ],
  grep: [Function: bound ],
  head: [Function: bound ],
  sed: [Function: bound ],
  sort: [Function: bound ],
  tail: [Function: bound ],
  to: [Function: bound ],
  toEnd: [Function: bound ],
  uniq: [Function: bound ] }

I'm sure I am missing something, but this one feels like it's a bug within the Cordova Build extension.

FYI Node: 8.9.1, NPM: 5.5.1, Cordova Build: 1.3.11

had exactly the same problem... it was caused by the NodeJS Version (8.x) on the agent. Downgraded to 6.x and after that, the step was working ;)

It is also possible, to add a "Use Node 6.x" Task in your build..
