Server LTR: OAPIF/WFS3 describe collections malfunction - empty pg layer with UTM zone SRID

[lorenzogrv]

What is the bug or the crash?

OAPIF/WFS3 Service can't handle properly empty PostGIS layers with "UTM-SRID-based" geometries

Steps to reproduce the issue

Reproduction which may serve as test sequence:

• Create an empty project

• Add a PostgreSQL vector layer having no features. Here I'm using a table which has EPSG:25829 Points

  CREATE TABLE test_empty_25829 (
    id serial not null primary key,
    geom geometry(Point, 25829)
  )

• Enable QGIS Server capabilitites and publish layer at QGIS Server settings

• Hit WMS/GetProjectSettings and WFS/GetCapabilities to ensure our server config works

  GET /?service=WMS&version=1.3.0&request=GetProjectSettings
  GET /?service=WFS&version=1.1.0&request=GetCapabilities
  

• Hit WFS3/OAPIF describe Collections endpoint → results on 500 Internal Server Error

  GET /wfs3/collections.json
  

  At server logs whe can see Error: Point outside of projection domain:

  09:46:02 CRITICAL Server[24]: Forward transform (EPSG:25829 to EPSG:4326) of (179769313486231570814527423731704356798070567525844996598917476803157260780028538760589558632766878171540458953514382464234321326889464182768467546703537516986049910576551282076245490090389328944075868508455133942304583236903222948165808559332123348274797826204144723168738177180919299881250404026184124858368.000000, 179769313486231570814527423731704356798070567525844996598917476803157260780028538760589558632766878171540458953514382464234321326889464182768467546703537516986049910576551282076245490090389328944075868508455133942304583236903222948165808559332123348274797826204144723168738177180919299881250404026184124858368.000000) Error: Point outside of projection domain
  09:46:02 WARNING [24]: finish() called twice
  

• Workaround:

  • Remove the layer from the project

  • Transform the original layer to EPSG:4326. Here I'm using a simple view - i.e:

    CREATE VIEW test_empty_4326
     SELECT id, ST_Transform(geom, 4326)::geometry(Point, 4326) AS geom
        FROM test_empty_25829
    ``
    

  • Add the new layer to the project, and publish it through QGIS Server settings

  • Hit again de /wfs3/collections.json endpoint → Observe it works as expected

Additional context

May be related to #45073

I also tried to work-around setting up the qgis_layer_metadata table extent to ensure it is within the UTM zone extent, but did not work either.
