Wayland sessions crash with Gjs:ERROR:../gi/interface.cpp:101:bool InterfacePrototype::has_instance_impl(JSContext*, const JS::CallArgs&): assertion failed: (args[0].isObject()) from <email address hidden>/locations.js:1108

Thanks for the bug report.

Can you explain in more detail what is not working? Maybe with a photo or video?

Oh sorry, I see the problem:

1.) Start Ubuntu
2.) Login
3.) Gnome-Shell appear for a short time
4.) I end back on the login screen
5.) I change to xorg and log in succesfully

I reportat this on:
https://discourse.ubuntu.com/t/since-update-to-jelly-wayland-do-not-anymore-work/26681

According to the feedback i got I Created this bug-report with 'ubuntu-bug gnome-shell'
now I try to do 'ubuntu-bug /var/crash/_usr_bin_gnome-shell.1000.crash'

I got the feedback, that it was already reportet on:
https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1959507

So I'm currently not sure if it is a duplicate or not.

Please run this command:

  gsettings set org.gnome.shell.extensions.dash-to-dock show-mounts false

and then reboot. Has that solved the problem?

If the problem is not fixed by comment #5 then please log into a Xorg session and run:

  journalctl -b0 > journal.txt

and attach the resulting text file here.

#5 "gsettings set org.gnome.shell.extensions.dash-to-dock show-mounts false" helped. Login now work.

Thanks a lot.

Once you've enabled the mount point again, could you please tell me what are you mountable devices?

In any case it would be helpful if you could manually edit (just use sudo with your editor) the file /<email address hidden>/locations.js so that it contains at around line 1108 (just after the initVolumePromises() definition):

print('o', object)
print('oc', object?.constructor)
print('ocp', object?.constructor?.prototype)

Then post the content of your journal here.

Another test you could do is try to remove these lines at all:

  if (!(object instanceof Gio.Volume) || object.constructor.prototype._d2dPromisified)
    return;

(or probably just remove '!(object instanceof Gio.Volume) ||').

This bug shouldn't be given High priority. There are no other reports of it, even on errors.ubuntu.com

1.) Did first test from Marco trevisan
2.) after that I run 'gsettings set org.gnome.shell.extensions.dash-to-dock show-mounts true'
3.) than restarted to Wayland
4.) got back to xorg exported the data with journalctl -b0 >Journal.txt
5.) this file is around 3MB in size so I compacted it to journal.tar.xz

May importante. I use Wireguard and have a mounted sft there. Since my update to 21.10 it do not work anymore.
Goal here is to have imediately after login a mounted drive.
I never found a recommended way how to automount a network drive in Ubuntu.

$HOME/.local/share/systemd/user/
contain a .mount and .automout file with folowing content.

.mount
___________
[Unit]
Description=Speicher einbinden

[Install]
WantedBy=multi-user.target

[Mount]

.automount

[Automount]

AlderHorst, thanks for the feedback.

So gjs in this case should definitely not crash, and I've fixed it there [1] (will prepare a package soon).

I'm quite curious to understand how is possible that Gio would emit a null device in such case, but that's another issue I'll have to handle.

I'll try to simulate your setup but maybe can you provide the output of this script?
https://www.pastery.net/menmxf/

Just save it in disk and run it with `gjs gio-mounts-debug.js`.

IIRC I noticed during development that it could happen that we may get a case where a Mount is added but its relative GVolume isn't set (yet).
