I have the same issue. it keeps saying ShortUrl is undefined and I have not got a clue why, as I followed everything to a T.

Everything starts up and works fine but when I click the shortened link or open in new tab and it just throws that error.

In the pictures provided, If I remove the lines of code in the blue bracket I get the "Cannot Get" error page just fine. But as soon as I paste the lines of code back in. Instant error and nothing loads.

Faced same problem. Got solved after installing MongoDB.

[Amit998]

app.get('/:shortUrl',async (req,res) =>{

shortUrl.findOne({ short:req.params.shortUrl } ,function(err,docs){
    

    if (docs == null ) return res.sendStatus(404)

    count = docs['click'] + 1

    var myquery = { short:req.params.shortUrl };
    var newvalues = { $set: {click: count } };

    shortUrl.updateOne(myquery,newvalues,function(err,res){
       
    })
    res.redirect(docs['full'])       
})

i guess it will help

Got the same error. Pretty sure something's wrong with the code as the forked copy of the GitHub code throws the same error.
