Deploy error with create react app

I attempted to add
module.exports = {
backends: origin
}
but the file reverts when after I try to deploy.

I am using create-react-app and added the router.js boilerplate code here:

It sounds like your configuration may not be valid. If you could provide your full router.js and xdn.config.js, it would be easier to narrow down.

Take a look at this example for how a backend should be defined for proxying: Moovweb XDN Documentation - Cookbook
