Basic Node and Express - Use the .env File get error Cannot set headers after they are sent to the client

I got a strange error in this problem made me crazy i don’t know what is the reason for this error

and this is my code

app.get('/json', (req, res) => {
  let data = {"message": "Hello json"};
  if(process.env.MESSAGE_STYLE === 'uppercase'){
    data.message = data.message.toUpperCase();

this code works fine and give no error when i run it on glitch but when i click submit button in freecodecamp this error apears to me.

If your test case is passed then let me know .
because i also stuck here

Hello there,

There appears to have been some breaking change between a package the fCC tests use, and Glitch.

For now, the recommended steps are:

  1. Fork the repo to another platform, like CodeSandbox, and complete it there.
  2. Move on from this lesson, as most of the other tests do not rely on the broken package.

Hope this helps

Hello @akkiee11,

It looks like you need to run npm i within the console.


Yes Its Working But Not passed test cases

In the second case if MESSAGE_STYLE not equal to uppercase it should be
Hello json instead of hello json with upper case for the first character only
