CORS error when calling /authorization from React app

I have a React application from which I am trying to authorize with Auth0.

I am calling an endpoint:

    const response = await fetch(
      `` +
        `audience=${audience}&` +
        `scope=${scope}&` +
        `response_type=${responseType}&` +
        `client_id=${clientId}&` +
        redirect: "manual",

From http://localhost:3000 and getting a CORS 302 error

My Auth0 app dashboard:

Authorization url:

I noticed that the authorization URL misses the state parameter, which is a random string.

Please reference the below articles.

Could you please add it and give it a try? If the error persists, please replicate this error and DM me the HAR file, and I will look further into it. Thanks!
