GeoJSON when displaying attribute table is not valid

[juwizeye]

Hi , I have installed Qgis server et lizmap on a lunix remote machine and Qgis desktop locally on Windows, it works well i can see a map in the canvas. But there is nothing in the layers's attributes tables . same for localization by layer , I can't see the values of the attribute that I selected.

I tested the same projet on localhost , and i worked nicely. there nothing in lizmap logs , If you have any suggestion I am all years. I use:

• Lizmap version: 3.5.0
• QGIS Server FULL version:3.16.16
• QGIS Desktop FULL version:3.22.1
• OS (Windows, Linux, MacOS, Android…): linux serveur distant , windows client local
• Browser (Firefox, Chrome…):
• Lizmap admin information (users, logs…) stored into Sqlite (default)? oui -WINSCP: for file sychronization .
  • local directory: c:\home\data\prod
  • distant directory :/home/data/prod

Do you have any error in the javascript console ? when clicking buttons ?

You should see network requests to fetch data.

Indeed, thanks to the URL you have published in #1714, we can see the GeoJSON when fetching data for the attribute table is invalid:

@nboisteault @mdouchin Any idea how this error is in the geojson data ?

Lizmap version: 3.5.0

@Gustry is there any special configuration for Https? I think that the problem come from there because when I am on localhost it works fine.

I found the solution , I had used fcgiwrap to install qgisserver and now I am using spawn-fcgi and it works fine. Thank you for your help @Gustry

Indeed, according to the QGIS documentation, fcgiwrap is not recommended, performances are bad. I'm not sure why HTTPS on QGIS Server. QGIS Server must stay hidden from the network otherwise you would have security issue if they bypass Lizmap. But indeed, you might have the use case for it and you can still have HTTPS.

But anyway, the GeoJSON mustn't have some error message in the geojson content. It makes it invalid.
