Is that all of your code? That seems like too little code to debug.
In any case, it looks like you are not using the strings required by the instructions.
Create a .env file in the root of your project directory, and store the variable MESSAGE_STYLE=uppercase in it.
Then, in the /json GET route handler you created in the last challenge, transform the response object’s message to uppercase if process.env.MESSAGE_STYLE equals uppercase. The response object should either be {"message": "Hello json"} or {"message": "HELLO JSON"}, depending on the MESSAGE_STYLE value.
I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
Ok, if that is your full code, then you have deleted a bunch of stuff from previous challenges. You should go back and look at how to add a GET request handler.
