Charge-to Syntax error. Javascript

I’m having an issue with charge-to. It doesn’t seem to be working. I used the same Javascript code found here: Facilitator Fee for ACH transfers | Dwolla API Documentation

Hey, @colterconway! Thank you for bringing this to our attention! Since the charge-to object key contains a hyphen, it must be surrounded with either single or double quotes when expressed in JavaScript. For example, please consider the following code snippet:

fees: [
    _links: {
      'charge-to': {
        href: ''
    amount: {
      value: '2.00',
      currency: 'USD'

Additionally, I do see where our documentation should have been more clear on this behavior and have added a ticket to get it addressed as soon as possible.
