Missing "Access-Control-Allow-Origin" header?

[queensburybill]

I'm a newbie, so forgive me if this is a silly question, but is it possible that the response for the hangman/hint endpoint is missing the "Access-Control-Allow-Origin": * header? I'm getting a CORS error when I try to do a GET request using axios. My other requests to the API work fine in the browser so I'm not sure why this one doesn't, and they all work when I tested them with Postman. In fact, it was in Postman that I noticed the other responses all include the above mentioned header and only in the hint response is it missing. Any enlightenment would be greatly appreciated.
