Vitest - URL cannot be parsed

While working on the Vitest - React Testing Library course, on the Setting Up Mock Service Worker section, I got an error from Vitest that states “TypeError: Failed to parse URL from /categories”. I’ve read it’s an issue with the URL being relative and not absolute, but I don’t understand what I should change it to since it’s a testing environment and it seems to work fine for Mosh in the video.
