HTTP response code

Hi, I am trying to setup Apollo Client in a React web app with Cognito JWT Tokens using Amplify.

So, I noticed I was getting 200 as response code on a GraphQL request with an expired token.
Is that correct?

This implementation of how to handle an expired token relies on a 401 http response.

Does anyone here have a good way of handling this?
Thanks

Is that a question related to Dgraph’s GraphQL? If not, maybe you can find support at Dgraph Community (Unofficial).

I will read that linked post later but in theory GraphQL should always return 200 and can send an error message by official spec.

Yeah, there are several approaches to error dealing/handling in GraphQL world. There are libs just for it.

Ok thanks! I should have read the spec obviously.

For those interested, I found a working approach with custom fetch. This way the token refreshes before making the api request.

  const customFetch = async (uri, options) => {

    const session = await Auth.currentSession();

    options.headers.Bearer = session.getAccessToken().getJwtToken();
    return fetch(uri, options);
  };

  const httpLink = createHttpLink({
    uri: config.dgraph_endpoint,
    fetch: customFetch,
  });
