"invalid content type header"

[shokarta]

Hello,

can anyone help to share what is wrong on this basic code?: ` function getYoutubeLink(input) { var xhr = new XMLHttpRequest();

    xhr.open("POST", 'https://co.wuk.sh/api/json', false);    // false for sync, true for async
    xhr.setRequestHeader('Content-Type', 'application/json');
    xhr.setRequestHeader('Accept', 'application/json');

    xhr.send(JSON.stringify({ "url": "https://www.youtube.com/watch?v=1i0k3rjXu9E"}));
    //xhr.send(JSON.stringify({ "url": "https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3D1i0k3rjXu9E"}));    // same error


    // now it waits for responce, and then do the following script:
    if (xhr.readyState === XMLHttpRequest.DONE) {
        try { JSON.parse(xhr.responseText.toString()); }
        catch (exception) { console.log(link + " // " + "Return message is NOT Json: " + xhr.responseText.toString()); return; }

        //var arr = JSON.parse(xhr.responseText.toString());

console.log(xhr.responseText.toString()); } }`

i keep getting: {"status":"error","text":"invalid content type header"}

thos, if I set the Accept header first (before Content-Type), the error say "invalid accept header".. so it looks like JS is only remembering the last header I set...

there is not much do pick up from, documentation does not show example, and anything I could google up "co.wuk.sh" is: https://greasyfork.org/zh-CN/scripts/483370-simple-youtube-downloader/code https://github.com/surenjanath/Spotify-Playlist-Download/blob/main/Spotify%20Music%20Downloader%20Medium%20Article.ipynb

i can't reproduce this, the snippet above just works for me

The snippet also works for me. Try maybe using fetch.
