Php Redirect With Slim Framework in Azure App Service

1

I’m using Slim 4. In my code, I’m trying to redirect to a URL:

return $response
        ->withHeader('Location', 'http://www.google.com')
        ->withStatus(302);

When I run it on my local computer on WAMP server using http://localhost, it worked fine. But, after uploading on azure app service and running, I’m just getting a blank page. The URL stays the same.

My .htaccess:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.php [QSA,L]

Response header:

What do the response headers look like?

Updated the question with the response header. Status code is 200 but I’m returning 302.
