SecurityError：在heroku 中部署react.js 应用程序时无法构建“WebSocket”

Question

I created a simple react.js app (bootstrap with create-react-app) only with chart.js graphs. Everything works fine in local host. Today, I tried to deploy in production via Heroku.

This is the error I'm getting (full version in screenshot) :

SecurityError: Failed to construct 'WebSocket': An insecure WebSocket connection may not be initiated from a page loaded over HTTPS.

I've seen that it's a common error that may be solved by changing protocol line in react-util-devs : issue link

That is to say, in my node_modules/react-dev-utils/webpackHotDevClient.js file, I changed line 62 with :

protocol: window.location.protocol === 'https:' ? 'wss' : 'ws',

I tried to deploy again, but keeps having the same error...

我有同样的问题，我认为发生的事情是当你推送到 heroku 时，node_modules 没有被更新，你只更新了你的本地版本，但这正是我的想法......有人找到了解决方案为了这？
