CORS issue fails the communicatin within Magento 2 (Graphql) instance and React app: Response to preflight request doesn’t pass access control check:

by |Published January 14, 2022

Getting following error trying to fetch data from react app.

Magento 2.4.2
Reac JS v17

Apollo/Client 3

 import { ApolloClient, InMemoryCache } from "@apollo/client";


 export const client = new ApolloClient({ 
       uri: "https://someurl/graphql",
       cache: new InMemoryCache(),
 });

I also tried to add “no-cors” as suggested but still its not working

fetchOptions: {
    mode: 'no-cors',
  },
