Passport authentification - client server - headers issues

My problem is to lunch the call API from the client side React JS .

I tried to get this URL with axios :
hostapi:portapi/twitchAuth

The authentification on twitch is lunch but I got an error in the callback function. Im just trying to acces to the json rended by my api but the error in the console in a picture above is about Headers from twitch. There is an URL in the error message and when Im clicking on it, Im getting the Json from my API.

You need to redirect the user to Twitch, not perform an axios.get

In the server

res.redirect('https://id.twitch.tv/oauth2/authorize?client_id=etc&response_type=code');

or in HTML

<a href="https://id.twitch.tv/oauth2/authorize?client_id=etc&response_type=code">Login with Twitch</a>

Not axios.getting it, thats why you keep getting a CORS error.

It seems you need a

<a href="hostapi:portapi/twitchAuth">Login with Twitch</a>

Not getting with with axios
