Can't log in to workspace

[ErikEklund]

ScudCloud Version

Expected behavior

After entering my login credentials, the workspace should load normally

Actual behavior

Stuck on loader screen - it never finished loading.

Steps to reproduce

1. Install scudcloud and start it
2. Enter credentials for a new workspace
3. Observe the loader. Nothing else happens and it never finishes.

Hi @ErikEklund and thanks for reporting this. I faced this onetime, started it with scudcloud --debug=True to check the problem, then it started properly. Still an issue for you?

[ErikEklund]

I tried starting with the debug flag. No change in behavior and no output in the terminal (except for "Mouse button 1" and "URL Changed", not helpful). So yes, still an issue. The console showed this though:

The goal of start with the debug is being able to right click and select Inspect and then select the Console tab. There we can see JavaScript errors.

[ErikEklund]

@raelgc JavaScript console errors posted above

Thanks @ErikEklund. I remember this issue.

Is it to hard for you downgrade your Qt to, at least, Qt 5.7.1 (instead of 5.10.1) and test again?

[ErikEklund]

I tried digging up 5.7.1 in the arch package archive, but after downgrade scudcloud failed with error message libicui18n.so.58: cannot open shared object file: No such file or directory. I tried downgrading icu as well, but that didn't seem to help. So no, can't seem to get scudcloud running on a lower version for now.

[raelgc]

I'm facing a hardtime with Qt/Webkit: older and newer versions are not working with Slack internal JS code. Sometimes I think scudcloud is good candidate for a flatpack/snap package (so I can include the required Qt version). The problem is this will make the package huge in size or in requirements.

[ErikEklund]

I see. I don't know if it helps in any way, but right now I'm running the official Slack client (not flatpak / snap versions) with qt 5.10.1 with no issues. I'm not sure if it's built in the same way as scudcloud though, so might not be important.

[ErikEklund]

On that note, the official slack client is 220 MB, vs ~350k for scudcloud :). I'm not sure people would mind a larger client, as long as it works.

[raelgc]

Slack official client uses Electron, which is a JS packaged version of Chromium (the open source version of Google Chrome). So it's not using Webkit as engine for HTML/CSS/JS rendering, but Google blink.

Same issue here on Manjaro KDE...
A change of User-Agent wouldn't help?

@masoud-al and @bashM0nk3y You need to post the content of the web console: after start with debug enabled, right click in the messages, select Inspect, then the Console tab and paste here the content.

Imgur Link - https://imgur.com/a/rznEvzc Just in case you have trouble viewing.

Looks like this is very similar, although not identical to ErikEklund's (OP) post.

Please let me know if there is anything at all that I can do to make debugging this issue easier on you!

[raelgc]

Thanks @bashM0nk3y. I can see it's the same problem affecting all of us not using 16.04: webkit newer than 5.7 has problems with ProxyObject in the JS side.

For now we have only all those hard options to try:

• we can wait until webkit fix this issue some day
• we can expect React considers webkit a supported browser
• you can try use annulen webkit which has the Proxy disabled (I used this as fix for Ubuntu 16.04)
• we can try replace webkit with Chromium (big effort)

I'm stopping ScudCloud development, please see #628
