How to catch an error (error decode url) in express?

Question

Node.js

URIError: Failed to decode param 'CZito%tS'
at decodeURIComponent (native)
at decode_param (/var/app/node_modules/express/lib/router/layer.js:167:12
) violates the URL standard (the percent symbol will be entered incorrectly), then it receives such an error. And this is unacceptable for the user to see what files are on the server, and so on.

Answer 1

something like this =) I decided myself.

app.use( (req, res, next) => {
    var err = null;
    try { decodeURIComponent(req.path); }
    catch(e) { err = e;}
    if (err){
        console.log(err, req.path);
        res.send('400 Bad Request');    
    }else next();
});
