Hello everyone,
I'm trying to do a https request from a create-react-app to get a login cookie.
To do this I have to be in the same subdomain of these call, thus I have added to my .env file:
.env
HOST=local.www.subdomain.org
Due to the call is https I have changed my package.json (I have to work in windows 😥)
package.json
"start": "set HTTPS=true&&react-scripts start",
EDIT: If you add HTTPS=true in .env file it will work too
If I call to https://localhost:3000
It is givig me an error in console, but the app is working:
webpackHotDevClient.js:60 WebSocket connection to 'ws://localhost:3000/sockjs-node' failed: Connection closed before receiving a handshake response
./node_modules/react-dev-utils/webpackHotDevClient.js @ webpackHotDevClient.js:60
__webpack_require__ @ bootstrap:785
fn @ bootstrap:150
1 @ index.js:3
__webpack_require__ @ bootstrap:785
checkDeferredModules @ bootstrap:45
webpackJsonpCallback @ bootstrap:32
(anonymous) @ main.chunk.js:1
When I try to call https://local.www.subdomain.org:3000
It is givign mi an error but the app is not launched:
SecurityError: Failed to construct 'WebSocket': An insecure WebSocket connection may not be initiated from a page loaded over HTTPS.
Someone knows what is the reason for this error.
Thank you
EDIT: I found the solution of that in https://github.com/facebook/create-react-app/pull/8079#issuecomment-562373869. The reason is because in react-scripts if https protocol is being used we should use WebSockets over SSL/TLS (WSS) protocol instead of WebSockets (WS) To solve you have to update the react-script version from 3.3.0 to 3.x.x or do a downgrade to 3.2.0.
