Rocket.chat: Livechat broken on latest develop

[bkraul]

Description:

Live chat no longer works on the latest develop version, and the log complains about missing assets.

Steps to reproduce:

1. Get latest docker develop version.
2. Attempt to navigate to the livechat page: https://mychat.com/livechat
3. The page will error out (I run it behind a reverse-proxy so I get 502 Bad gateway).

Expected behavior:

The public-facing livechat interface should show.

Actual behavior:

There is an error page. Log records the following:

Exception in callback of async function: Error: Unknown asset: public/head.html,
    at getAsset (/app/bundle/programs/server/boot.js:329:19),
    at Object.getText (/app/bundle/programs/server/boot.js:340:16),

Thanks to the develop images archive I set up 😜 on my docker hub, I can confirm that livechat last worked fine on commit 44d84927613d85f66745795365d9056d704d8f58.

I have archived 2 more builds since that commit (44d8492 and 7f5d817) so something must have changed in between, I guess.

Fixed here -> https://github.com/RocketChat/Rocket.Chat/pull/13723

OK so I must have missed something about this. The PR says that the livechat client is provided now as a "Community Feature", but that the "2" will be maintained for a while.

What does this mean? From the looks the snippet the only thing changing is the ?version=1.0 at the end of the URL. Could you please explain a little, @renatobecker ? My apologies if this has been explained before.

Better yet, if there is a documentation URL I can check for this, that would be great!

Same here.

Tried the 'modified' script which throws the error as well.

<script type="text/javascript">
(function(w, d, s, u) {
    w.RocketChat = function(c) { w.RocketChat._.push(c) }; w.RocketChat._ = [];
    w.RocketChat.url = u;
    var h = d.getElementsByTagName(s)[0],
        j = d.createElement(s);
    j.async = true;
    j.src = 'https://chat.mydomain.net/livechat/1.0/rocketchat-livechat.min.js?_=201903270000';
    h.parentNode.insertBefore(j, h);
})(window, document, 'script', 'https://chat.mydomain.net/livechat?version=1.0');
</script>

Same here. Even with ?version=1.0 it is still broken. I am still trying to understand what "community feature" means. Is it not bundled with RocketChat anymore?

Hi @bkraul, You're still getting the error because the PR wasn't merged yet.
The reason for the error is because we have made some structural changes on the codebase/packages and it has impacted on Livechat plugin.
But, since you're running the develop branch, this is a kind of situation that may happen.

Related to the Community Feature stuff, it means that we will start providing our new Livechat solution(https://github.com/RocketChat/Rocket.Chat.Livechat) as a Community Feature, so please review the Javascript Snippet again, you'll see that the j.src has been changed as well.

Thanks.

@renatobecker Thanks for the reply. Again I still do not understand what the term Community Feature really means but that's OK. I understand that running the develop branch will sometimes incur in some issues. As specified, I was able to go back to the latest build without the error. I will switch to a new image when the PR is merged and built.

Again I still do not understand what the term Community Feature really means but that's OK.

We ran a beta testing with Enterprise customers.
