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'
};
