The documentation at https://guide.elm-lang.org/effects/http.html refers to this code snippet:

init _ =
  ( Loading
  , Http.get
      { url = "https://elm-lang.org/assets/public-opinion.txt"
      , expect = Http.expectString GotText
      }
  )

which on running locally returns this cors error:

Access to XMLHttpRequest at 'https://elm-lang.org/assets/public-opinion.txt' from origin 'http://localhost:8000' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header has a value 'https://worker.elm-lang.org' that is not equal to the supplied origin.

Came here to open the same issue. It's not a great user experience, I can't even imagine how frustrating this would be for beginners who don't know how to check for CORS.

Can we please at least replace the URL in the docs with something like url = "https://httpbin.org/uuid"?
