CORS error in 05-http.elm

sbfram opened this issue · 0 comments

Hi,

There's a CORS issue when running the 05-http.elm example in the tutorial. Chrome tells me

Access to XMLHttpRequest at 'https://elm-lang.org/assets/public-opinion.txt' from origin 'null' 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.

I changed the example to request a file from a server that I could configure with Access-Control-Allow-Origin : * and that worked. Thought I'd post this here so that other Elm beginners who Google the error will understand that it's not a bug in the example per se, but appears to be a configuration issue on the server side.

Thanks,
Steve
