Use the .env File

I am having the result, but it is not passing the tests.

let express = require('express');
let app = express();

console.log("Hello World!")

/*app.get("/",function(req,res){
          res.send('Hello Express');
})*/

let absolutePath = __dirname + '/views/index.html';
let absolutePath2 = __dirname + '/public';  

app.get("/",function(req,res){
  res.sendFile(absolutePath)
  }) 

app.use('/public',express.static(absolutePath2));



app.get('/json',function(req,res){
         let object = {"message":"Hello json"}
const mySecret = process.env['MESSAGE_STYLE']
           if(mySecret=="uppercase"){
                return res.json(object["message"].toUpperCase()) 
           }
        return res.json(object)
})





What do you think this is sending?
