After extension auto-updated last night, panel won't start with error: 'No signal connection 15 found'

[MostHated]

Describe the bug Restarted PC to let extension update, it will no longer start up with Extension Manager showing error of : 'No signal connection 15 found' for dash-to-panel

Linux distribution and version Ubuntu 23.10

GNOME Shell version GNOME Shell 45.1

Dash-to-Panel version This can be seen in the Dash-to-Panel Settings in the About tab. 60

Where was Dash-to-Panel installed from? Gnome Extension Site

Screenshots / Video captures

In the second image, I was attempting to uninstall and reinstall the extension.

Same for me, but with "No signal connection 7 found"

Unfortunately, I had to download v59, open the manifest, change the version string from v59 to v60 and put that in $HOME/.local/share/gnome-shell/extensions so that it would think I am already updated, and stop auto-updating to a non-working version. v59 is still working just fine.

Same here (all of a sudden):

GNOME 45.2 / Ubuntu 23.10 on a notebook computer.

I've seen some reports of this but haven't encounter this yet. I'll leave it opened for now but I need a way to reproduce this.

as discussed in the thread above it mostly happens when resuming from sleep, its happening pretty much every time for me so if you want me to gather information just let me know

[x9sim9]

I decided to do some debugging in this as its happening every day for me at the moment this is what I am seeing in the log

is there some code that disables and enables dash to panel on resume from sleep? wondering if something as simple as a wait and retry may fix the issue

[x9sim9]

Ok so I think I have figure out the problem so the culprit is this command

ubuntuDock.stateObj.disable();

/home/[USER]/.local/share/gnome-shell/extensions/dash-to-panel@jderose9.github.com/extension.js:110:29

I suspect its already disabled and this is causing the no connection bug if you put the command in a try catch the issue goes away

try {
    ubuntuDock.stateObj.disable();
} catch(e)  {

}

Can someone having this problem try the master branch on Ubuntu 24.04?

Can someone having this problem try the master branch on Ubuntu 24.04?

I tried with Ubuntu 23 but it caused the UI to lock up after attempting login, restoring the previous version resolved the issue so not sure if its a compatibility issue with Ubuntu 23 or an issue affecting 24 as well

[x9sim9]

Also if it helps I found a way to reliably recreate the bug during my local attempts to resolve the issue, after login I would just randomly disable and enable other gnome extensions until it broke, it didnt seem to matter which extensions I disabled then enabled to cause the issue, but once it broke I had to restart my device to recreate it again logging in and out didn't work.

I also experienced the issues described here and I'm now running the version from the master branch without issues.

The only issue I had, which I'm not sure if it's related, is that ubuntu-dock (installed by default afaik) would render behind the dash-to-panel and I couldn't disable it. I resorted to uninstalling gnome-shell-extension-ubuntu-dock. :shrug:

EDIT: still running fine after a week

[x9sim9]

just upgraded to ubuntu 24 same issue here is the log, just to clarify i am using the original version not the version from the master branch, if this has not been pushed to the master branch let me know and I will try that.
