it is the problem of res.redirect , it needs a protocol like http or https otherwise it consider the redirect as a relative path - this will throw out an error Use this instead const url=entry.redirectURL.startsWith('') || entry.redirectURL.startsWith('') ? entry.redirectURL :`${entry.redirectURL}` ; res.redirect(url)

Even the code provide by you has the same problem. But when a url starts with "https:" or "http:" this problem surprisingly doesn't happen. ‼edit: it is the res.redirect( ) , it needs a protocol like http or https otherwise it consider the redirect as a relative path so just append https before the url that stored in your database if it doesn't have any protocol to to that you can use the code here: const redirectUrl = url.redirectUrl.startsWith('') || url.redirectUrl.startsWith('') ? url.redirectUrl : `${url.redirectUrl}`;
