Help needed: The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received an instance of Node

So this issue is that you need to add node: 'current' to your targets file. Its something that I’m working on fixing the default behaviour for ember-cli-fastboot at the moment.

Here is an example targets file:

'use strict';

const browsers = [
  'last 1 Chrome versions',
  'last 1 Firefox versions',
  'last 1 Safari versions'
];

const isCI = !!process.env.CI;
const isProduction = process.env.EMBER_ENV === 'production';

if (isCI || isProduction) {
  browsers.push('ie 11');
}

module.exports = {
  browsers,
  node: 'current'
};
