Tell us what’s happening:
freeCodeCamp is not happy with my code but as far as I can tell it should pass.

See the running instance here:

Your code so far

/** 5) serve JSON on a specific route */
app.get("/json", (req, res) => { 
  let message = "Hello json"; 
  if(process.env.MESSAGE_STYLE === "uppercase"){
    message = message.toUpperCase();
  }
  res.json({"message": message}); 
});
