Mapviewer crashes when using Portal

[rsrg-zwiama]

The mapviewer will fail on start up with a blank page, when using the Portal in the config.json. This is due to the missing dictionary key 'key' for the Portal, menuItems 'Homepage'

        "name": "Portal",
        "cfg": {
          "logo": "logo.svg",
          "topBarText": "QWC2 Portal",
          "showMenuOnStartup": true,
          "keepMenuOpen": true,
          "bottomBarLinks": [
              {"href": "https://qwc-services.github.io/", "label": "Homepage", "target": "iframe"},
              {"href": "https://qgis.org", "label": "QGIS.org"}
          ],
          "menuItems": [
              {"title": "Homepage","key": "placeholder", "icon": "info", "url": "https://qwc-services.github.io/", "target": "iframe"},
              {"title": "QGIS.org","key": "placeholder", "icon": "link", "url": "https://qgis.org"},
              {"key": "Tools", "icon": "tools", "title": "Links", "subitems": [
                {"icon": "link", "title": "qwc2-demo-app", "url": "https://github.com/qgis/qwc2-demo-app/"},
                {"icon": "link", "title": "qwc-docker", "url": "https://github.com/qwc-services/qwc-docker"}
              ]}
          ]
        }

To avoid this, the def __replace_login__helper_items(self, items, signed_in, hide): should check if the dictionary has a key called 'key' in this section

qwc-map-viewer/src/qwc2_viewer.py

Line 536 in 8e7e930

if item["key"] == "Login" and signed_in:

            if ('key' in item) and item["key"] == "Login" and signed_in:
                if hide:
                    removeIndex = idx
                    break
                else:
                    item["key"] = "Logout"
                    item["icon"] = "logout"
            elif "subitems" in item:
                self.__replace_login__helper_items(
                    item["subitems"], signed_in, hide)

Other solution would be to exclude the portal plugin here

qwc-map-viewer/src/qwc2_viewer.py

Line 520 in af29edb

if "menuItems" in plugin["cfg"]:

if "menuItems" in plugin["cfg"] and plugin["name"] != "Portal":

I tested with version 2025lts
