[videni]

const FetchMiddleware = createFetchMiddleware({
  afterFetch({ action, result }) {
    return result.json().then(data => {
      return Promise.resolve({
        action,
        result: data,
      });
    });
  },
  credentials: "same-origin",
});

no credentials option here

  const { url, types, ...options } = action; // eslint-disable-line
