React-admin: Error: The Content-Range header is missing in the HTTP Response.

[bvv218]

I am getting this error when I try to fetch data, even though I receive all the data needed from the server:

The Content-Range header is missing in the HTTP Response. The simple REST client expects responses for lists of resources to contain this header with the total number of results to build the pagination. If you are using CORS, did you declare Content-Range in the Access-Control-Expose-Headers header?

Is there a way to solve it without making changes to the API? I was doing authorization based on the tutorial, here is my app.js:

``const httpClient = (url, options = {}) => { if (!options.headers) { options.headers = new Headers({ Accept: 'application/json' }); } const token = localStorage.getItem('token'); options.headers.set('Authorization',Bearer ${"token"}`);
return fetchUtils.fetchJson(url, options);
}
const restClient = simpleRestClient('https://mywebsite.com', httpClient);

const App = () => (



);```

server add follow:
res.header('Access-Control-Allow-Origin', 'http://localhost:3000');
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
res.header('Access-Control-Allow-Headers', 'Content-Type,x-access-token');
res.header('Access-Control-Allow-Credentials','true');
res.header("Access-Control-Expose-Headers", "Content-Range");
