Not getting expected headers in XmlHttpRequest during a response

[mmacphail]

Hello,

I use the following snippet:

    const api = new RestClient("http://localhost:8080/mgag/api");
    api.res("users");
    api.users.post(data).then(function (evt) {
        console.log(evt);
    }, function (other) {
        alert("Unable to subscribe");
        console.log(other);
        console.log(other.getAllResponseHeaders());
    });

Unfortunately, the other parameter doesn't contain any useful headers even if the server sends them.

What I'm getting in Mozzilla Developper Console:

I want to grab the "Cause" header here.

Please note that I use CORS.

Why you have "http://localhost:8080/app/api" URL in code, but "http://localhost:8080/mgag/app/api" URL in dev tools? Notice /mgag/ part.

Also, look here: https://stackoverflow.com/questions/8945587/xmlhttprequest-getallresponseheaders-not-returning-all-the-headers

The url is http://localhost:8080/mgag/api ; I misstype app in my question let me edit this for posterity.

Indeed, I had to expose my CORS headers and that was th problem. Thanks 👍 !
