Express ,redirect

Tell us what’s happening:
I failed in test[3] ( When you visit /api/shorturl/<short_url> , you will be redirected to the original URL.)
i don’t know where i did it wrong. It seems the redirect worked already,but test still failed

Your code so far
app.get(‘/api/shorturl/:short_url’,(req,res)=>{
//console.log(req.hostname);
res.redirect(‘/’);
})
