Cannot pass .env Challenge in Basic Node even though everything is set up correctly
Working on the .env problem

Hello Moshud.

I moved your post into its own topic, and formatted your code.

After a lot of testing, I cannot figure out why that error appears. Something to note: Someone else tried your code, and they were able to pass with it without the error.

The associated code which runs the tests is here:

I might spend more time later going through again. Otherwise, your code is correct, and you are welcome to skip that challenge. I hope you get this sorted.

MESSAGE_STYLE=uppercase

that is my env file

var express = require(‘express’);
var app = express();
console.log(“Hello World”);

app.get("/", function(req, res) {
res.sendFile(__dirname + “/views/index.html”);
});

app.use(express.static(__dirname + “/public”));

var response = “Hello Json”.toUpperCase();

if (process.env.MESSAGE_STYLE == “uppercase”) {
response = “Hello Json”.toUpperCase();
} else {
response = “Hello Json”;
}

app.get("/json", (req, res) => {
res.json({
message: response
});
});

that is myapp file

I am still not passing and am confused at why. I think it is because i don’t fully understand the env file.

you need the logic for the message in the get callback
