[Bug]: Saved extent is not valid in CFG

[tbnobody]

What is the bug?

I just saved a new configuration of a project and the project failed to parse:

2024-03-13 16:16:19     10.140.129.6    [0]     The file /opt/qgis/lizmap/projects/ProjectOverview.qgs.cfg cannot be decoded.    /var/www/lizmap-web-client-3.7.5/lizmap/modules/lizmap/lib/Project/Project.php     135

For some layers I see the following in the json code:

        "Offices": {
            "id": "Offices_3e456444_b7b3_4ed5_b24e_f67e35c952d4",
            "name": "Offices",
            "type": "layer",
            "geometryType": "point",
            "extent": [
                NaN,
                NaN,
                NaN,
                NaN
            ],
            "crs": "EPSG:4326",
            "title": "Offices",
            "abstract": "",
            "link": "",
            "minScale": 1,
            "maxScale": 1000000000000,
            "toggled": "False",
            "popup": "True",
            "popupSource": "form",
            "popupTemplate": "",
            "popupMaxFeatures": 10,
            "popupDisplayChildren": "False",
            "popup_allow_download": true,
            "legend_image_option": "hide_at_startup",
            "groupAsLayer": "False",
            "baseLayer": "False",
            "displayInLegend": "True",
            "group_visibility": [],
            "singleTile": "True",
            "imageFormat": "image/png",
            "cached": "False",
            "clientCacheExpiration": 300
        },

The NAN is invalid.

Check Lizmap plugin

• [X] I have done the step just before in the Lizmap QGIS desktop plugin before opening this ticket. Otherwise, my ticket is not considered valid and might get closed.

Don't know where the error came from but after pressing this button for all affected layers it's working now:

[Gustry]

Where are these buttons ? Is it in the vector layer properties then datasource, right ? you mean the button on the right ? Sorry I don't speak german.

I'm QGIS updated the project extent, your project was newly created right ?

[tbnobody]

Sorry, I didn't have a english qgis version available. But right, Layer Properties, Datasource

The layer is a PostGIS layer. It was a project which was used before. Also the .cfg was generated previously without any error. Not sure if it's a problem of QGIS or the extension. But it happend just now again. I had to press the button again.

[tbnobody]

Ok just figured it out....

• Opened the extension, pressed "Save"
• NaN in json
• go to layers, press "Update" button
• go to lizmap extension, press "Save"
• Correct coordinates in json
• go to lizmap extension, press "Save"
• NaN in json

[Gustry]

go to lizmap extension, press "Save" Correct coordinates in json go to lizmap extension, press "Save" NaN in json

Do you mean you press twice ? Because there isn't any user action in between these two.

What kind of layer is Offices ? PH, SHP, GPKG ? Is-it possible to share it ? I will just add a safeguards for now

[Gustry]

In your vector layer properties → Information tab → Provider, what is the "Extent" here ? The plugin is taking these values.

[tbnobody]

Do you mean you press twice ?

Correct, just closed the extension window and opened it again

What kind of layer is Offices ?

It's PostGIS

In your vector layer properties → Information tab → Provider, what is the "Extent" here ?

You are right, it's shown as Null

Just saw, when pressing the Rebuild button I get the following log output:

2024-03-14T10:48:00     WARNING    Ergebnis der Ausdehnungsabfrage ungültig: BOX(-88.00371551513672 -33.86600112915039,151.2113037109375 52.9696044921875)

Translated: Result of the expansion query invalid

[Gustry]

Even QGIS can't get the correct extent of your layer.

Side question can you select the layer in your legend and then Python → Console

iface.activeLayer().extent().isNull()
iface.activeLayer().extent().isEmpty()

And give the output of these two commands ?

[tbnobody]

And give the output of these two commands ?

Both return True

[tbnobody]

Just found this: https://github.com/qgis/QGIS/issues/56541

[Gustry]

It seems it will be fixed upstream.
