我正在尝试使用本指南中的代码运行 gnome 扩展 https://gjs.guide/extensions/upgrading/legacy-documentation.html#extension Ubuntu 22.04、GNOME 42.9、wayland

extension.js 的内容（从上面的链接复制）：

const St = imports.gi.St;

const ExtensionUtils = imports.misc.extensionUtils;
const Me = ExtensionUtils.getCurrentExtension();
const Main = imports.ui.main;
const PanelMenu = imports.ui.panelMenu;

const {
gettext: _,
} = ExtensionUtils;


class Extension {
enable() {
    // Create a panel button
    this._indicator = new PanelMenu.Button(0.0, Me.metadata.name, false);

    // Add an icon
    const icon = new St.Icon({
        icon_name: 'face-laugh-symbolic',
        style_class: 'system-status-icon',
    });
    this._indicator.add_child(icon);

    // Add the indicator to the panel
    Main.panel.addToStatusArea(Me.metadata.uuid, this._indicator);

    // Add a menu item to open the preferences window
    this._indicator.menu.addAction(_('Preferences'),
        () => ExtensionUtils.openPrefs());

    this._count = 0;
}

disable() {
    if (this._indicator) {
        this._indicator.destroy();
        this._indicator = null;
    }
}
}


function init() {
ExtensionUtils.initTranslations();

return new Extension();
}

metadata.json的内容：

{
"uuid": "[email protected]",
"name": "Example Extension",
"description": "An example extension",
"shell-version": [ "42.9" ],
"url": "https://gjs.guide/extensions"
}

我正在开展一个项目，需要使用 SSM 文档将 Spring Boot 应用程序 Pet Clinic 到 Ubuntu 22 服务器上。我已附加 Systems Manager 运行文档。以下错误来自命令 sudo journalctl -u spring-petclinic.service 。我尝试授予任何和所有访问权限，以 root 身份运行，但仍然不起作用。

关于如何让该应用程序保持运行，您有什么想法吗？
