Test submit doesn't pass but code works

I am stuck at excercise: Basic Node and Express - Use the .env File

Challenge: Basic Node and Express - Use the .env File

Link to the challenge:

Welcome marko.

You are setting the logic of the response the way you should, but you are not serving it anywhere…
This is the part of the instructions you have not followed:

Then tell the GET /json route handler that you created in the last challenge to transform the response object’s message

Follow that, and let us know how far you get.

Thanks I got it now:

app.get("/json", function (req, res) {
/** 5) serve JSON on a specific route */
var response = “Hello json”;

/** 6) Use the .env file to configure the app */
if (process.env.MESSAGE_STYLE === “uppercase”) {
response = “Hello json”.toUpperCase();
} else {
response = “Hello json”;
res.json({“message”: response});

Tried the same code but it does not work.
