When error occurred in webfonts-generator, script is broken.

When I only generate one svg image to icon-font. The error occurred as below:

$ icon-font-generator src/assets/icons/*.svg -o icon-dist
Generating font kit from 1 SVG icons
(node:34523) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'red' of undefined
    at fail (/Users/XXX/XX/XXXXX/node_modules/icon-font-generator/bin/icon-font-generator:88:31)

I debug the code and find webfonts-generator will return a error " Fail! Checksum error in glyf".
This error is a string, so "err.message.red" will return this error, and script will be broken.

function fail(err) {
  if (typeof err === 'string' || err instanceof errors.ValidationError) {
    console.error(err.message.red)
    process.exit()
  }

  if (err instanceof Error) { throw err }
}

I ran into the same issue.

Thanks for reporting - upgrading to 2.1.8 should fix (#37) - please re-open it the issue persists.

Yes, it will generate a better error message but the problem will still persist. The issue lays in one of the dependencies. Take a look at this thread

As long as the error outputting is solved here I'll keep this closed - thanks
