Error: Invalid value 'undefined' for property body in object initializer.

[St3v3-wq]

I just got this error in gnome-extensions and the extension would not start.

[fthx]

You run Arch? I got another similar bug in Proton VPN button extension.

The bug is due to the new notification syntax (needs two args in GS 46) that I did forget to change. BUT that's not the root cause. The cause is the app is not found.

Do you know how to use looking glass in gnome shell?

[fthx]

btw I don't get any error using Ubuntu 24.04.

[St3v3-wq]

No, Fedora 40.

[fthx]

What's your email client? Is it set as default email client in GS prefs?

[St3v3-wq]

What's your email client? Evolution (RPM) Is it set as default email client in GS prefs? Yes

This is strange: I installed claws-mail, then the extension is working. But only with claws, even when evolution is set in GS. When I remove claws, the error is something like "failed to open claws-mail, failure in PATH".

[fthx]

Ok. Maybe a session restart is needed for email client switch.

Please in GNOME Shell:

• alt+F2 (execute)
• lg (looking glass inspector)
• enter this: GLib.spawn_command_line_sync("xdg-mime query default x-scheme-handler/mailto")
• copy here the result

[St3v3-wq]

I'm sorry, lg is unsupported. Is there a new version somewhere? Also when I install it anyway..

[fthx]

LG is not an extension, it's built-in I've installed a F40 vm and the result is a void name, so the error.

[fthx]

[fthx]

Damn Software app, soooo slow. I'm back soon ;-)

[fthx]

Ok I installed Evolution, will be better now ;-)

[fthx]

Mmmh I get all attended prompts?

[St3v3-wq]

Ok, here the output from lg: ...true,org.Evolution.desktop...

[fthx]

It works in my VM:

[fthx]

The button click works too.

[St3v3-wq]

hmm?

[fthx]

Did you set this (again)?

[St3v3-wq]

[St3v3-wq]

It does not even start without claws-mail??

[fthx]

Did you try without any other extension disabled?

[fthx]

What's the command in terminal to update rpm packages, please?

[St3v3-wq]

sudo dnf update

[St3v3-wq]

Maybe this is a "only my computer" problem. Sorry. Should I delete some Gnome Settings?

[fthx]

I cannot install Claws, it's failing...

[fthx]

Do you have the black square in LG at the end of org.Ev... ? (That's attended.)

[fthx]

Could you change this line in: ~/.local/share/gnome-shell/extensions/new-mail-indicator/extensions.js ?

48 Main.notify("New Mail Indicator: error, no email client found");

to:

Main.notify("New Mail Indicator: error, no email client found", "");

[fthx]

Then restart your session.

[St3v3-wq]

Do you have the black square in LG at the end of org.Ev... ? (That's attended.)

Yes, it's white here.

[St3v3-wq]

Yep, it's running now (error, no email client found).

[fthx]

Well that's annoying I cannot reproduce the root cause in VM. Maybe an update since F40 iso has changed something?

[St3v3-wq]

It was running with Evolution from Flatpak, but not anymore. That is strange.

[fthx]

As a workaround you can change this:

_find_default_client() {
    this._decoder = new TextDecoder();
    this._app_query = GLib.spawn_command_line_sync("xdg-mime query default x-scheme-handler/mailto");
    this._app_filename = this._decoder.decode(this._app_query[1].slice(0,-1));
    this._app = Shell.AppSystem.get_default().lookup_app(this._app_filename);
    if (this._app) {
        this._app_name = this._app.get_name();
    } else {
        Main.notify("New Mail Indicator: error, no email client found");
    }
}

to this:

_find_default_client() {
    this._app_name = "Evolution";
}

[fthx]

but you won't have the click feature since I catch the app object's windows.

[fthx]

in LG did you try:

Shell.AppSystem.get_default().lookup_app("org.gnome.Evolution.desktop")

?

[St3v3-wq]

Ok, thank You for this.

in LG did you try:

Shell.AppSystem.get_default().lookup_app("org.gnome.Evolution.desktop")

?

r(0) = null

[St3v3-wq]

Oh sorry, I forgot to say: There is a bug in the current Evolution installation and there ist no org.gnome.Evolution.desktop. Is this maybe the problem? I mean, there is no Icon to start Evolution.

[St3v3-wq]

As a workaround you can change this:

_find_default_client() {
    this._decoder = new TextDecoder();
    this._app_query = GLib.spawn_command_line_sync("xdg-mime query default x-scheme-handler/mailto");
    this._app_filename = this._decoder.decode(this._app_query[1].slice(0,-1));
    this._app = Shell.AppSystem.get_default().lookup_app(this._app_filename);
    if (this._app) {
        this._app_name = this._app.get_name();
    } else {
        Main.notify("New Mail Indicator: error, no email client found");
    }
}

to this:

_find_default_client() {
    this._app_name = "Evolution";
}

Thank You for that. It's running now, with the error: Error: Invalid value 'undefined' for property body in object initializer.

[fthx]

For Ev install, you have to check in /usr/share/applications

[St3v3-wq]

For Ev install, you have to check in /usr/share/applications

Ah, tere is it...

[St3v3-wq]

As a workaround you can change this:

_find_default_client() {
    this._decoder = new TextDecoder();
    this._app_query = GLib.spawn_command_line_sync("xdg-mime query default x-scheme-handler/mailto");
    this._app_filename = this._decoder.decode(this._app_query[1].slice(0,-1));
    this._app = Shell.AppSystem.get_default().lookup_app(this._app_filename);
    if (this._app) {
        this._app_name = this._app.get_name();
    } else {
        Main.notify("New Mail Indicator: error, no email client found");
    }
}

to this:

_find_default_client() {
    this._app_name = "Evolution";
}

But this way does not display new Mails (red icon).

However, thank You for Your time!

[St3v3-wq]

Ok, fixed.

I fixed it by fixing Evolution. There is no problem with Your extension. The way was (at the end very easy):

$ cp /usr/share/applications/org.gnome.Evolution.desktop ~/.local/share/applications/ $ update-desktop-database -v ~/.local/share/applications

Thanks for Your time!
