Error on JavaScript console when no announcement shown

$(document).ready(function() {
    function s(e, t, n) {
        let o = ""
          , s = new Date
          , i = 24 * 60 * 60 * 1e3;
        n && (s.setTime(s.getTime() + n * i),
        o = "; expires=" + s.toUTCString()),
        document.cookie = e + "=" + t + o + "; path=/"
    }
    function o(e) {
        let t = document.cookie.match(new RegExp("(?:^|; )" + e.replace(/([.$?*|{}()[\]\\/+^])/g, "\\$1") + "=([^;]*)"));
        return t ? "true" : void 0
    }
    let e = document.querySelector("#announcement")
      , n = `announcement_ack_${e.getAttribute("data-announcement-name").replace(/\s/g, "_")}`
      , i = o(n);
    i === "true" ? e.remove() : e.classList.add("display-announcement");
    let t = document.querySelector("#banner-dismiss");
    t.removeAttribute("style"),
    t.addEventListener("click", function() {
        s(n, "true", t.getAttribute("data-ttl")),
        e.remove()
    })
})

In the code above, e is null in the let e = document.querySelector("#announcement") part. Please check “#announcement”.

For me, this wouldn't be a priority to fix.

[parkilwoo]

I can't proceed with the tutorial due to an issue. What should I do?

[sftim]

@parkilwoo can you describe the symptoms you are seeing when you try to follow a tutorial?

[parkilwoo]

The interactive tutorial does not work.
I think it might be a problem as katacoda ends its service.

[dipesh-rawat]

The interactive tutorial does not work.

@parkilwoo Katacoda environment for the Kubernetes tutorial has been shut down. Refer the announcement here.

We have an umbrella issue raised #41496 to remove tutorials that rely on Katacoda for all localized documents.

It seems that the issue regarding the JavaScript console errors has already been reported and is being tracked in our backlog as part of #45830.
