Tests failing when the environment variable is working

JavaScript
1

Hello, I stored the variable MESSAGE_STYLE=uppercase in the .env file and to the best of my knowledge I correctly created my conditions in myApp.js. I have navigated to /json and it is correctly transforming to all caps by searching for the environment variable so I am confused as to why I am failing the tests.

Hi, I’m having a similar issue to the op with this challenge.

Link to my code

I get an error/challenge failure by submitting either of the following links, even though if I browse to the '.../json' url in my browser, it works as expected with the json string being in upper case when MESSAGE_TYPE is uppercase, else lower case (Chrome Version 88.0.4324.150 (Official Build) (64-bit)):
https://boilerplate-express-1.rapscallion45.repl.co
https://boilerplate-express-1.rapscallion45.repl.co/json

This is the full output from my console, including when freeCodeCamp attempts to check my code:

 npm start

I’m confused as to why this error is happening?

I have exactly the same error. I suspect because of the

SyntaxError: Unexpected token < in JSON at position 0
    at JSON.parse (<anonymous>)

There is some part of the test that is getting an html string instead of a JSON.
