[Qgis-user] WFS - Env variable QGIS_SERVER_API_WFS3_MAX_LIMIT not working

[Tommaso]

Hello,
I'm trying to limit the max number of features returned by my Qgis Server 
using the environment variable QGIS_SERVER_API_WFS3_MAX_LIMIT

QGIS_SERVER_API_WFS3_MAX_LIMIT=1000

The server seems to consider the variable and write to the log file

10:41:20 INFO Server[90]:   - QGIS_SERVER_API_WFS3_MAX_LIMIT / 
'/qgis/server_api_wfs3_max_limit' (Maximum value for "limit" in a features 
request, defaults to 10000): '1000' (read from ENVIRONMENT_VARIABLE)

The server should return max 1000 features, but it still returns all 
features. The limit is ignored. How can I debug the problem?

My WFS request:
http://XXXXXXXXX/qgisserver?SERVICE=WFS&VERSION=1.0.0&MAP=/etc/qgisserver/project.qgs&service=WFS&request=GetFeature&typename=Gemeinde
