How to enable CORS on nodejs express redirect?

I am using nodejs express as my API in the backend. I wonder how to enable CORS on redirect method.

Below is my express redirect code:

res.redirect(redirectUrl);

when client sends request to above API it will redirect the request to a s3 but I get below error:

    Access to XMLHttpRequest at 'https://s3-ap-southeast-
2.amazonaws.com/index.html' (redirected from 
'http://localhost:9090/v0/api') from origin 'http://localhost:9090' has 
been blocked by CORS policy: Response to preflight request doesn't pass 
access control check: No 'Access-Control-Allow-Origin' header is present on
 the requested resource.

the frontend is running under http://localhost:9090 and the frontend domain has been added on CORS in the s3 bucket. It works fine if I send the request to https://s3-ap-southeast-2.amazonaws.com/index.html directly from the browser. So I think the problem is on nodejs express redirect method. How can I enable CORS for the redirect?

I know how to enable CORS but my problem relates to redirect. How can I make the redirect work?
