What is the issue?
Internal temporary redirects (redirects with a 302 or 307 status code) can result in subpar ranking performance. Search engines assume that the temporary redirects were either unintentional or will soon be removed.
How to fix
If the redirect is necessary, update the 302 status to 301 to send the correct ranking signals to the new page.
If the redirect is not needed, update all internal links pointing to the 302 redirected URL to be linking to the target document instead.
